             list-type  List prefix types.  Type describes the
                        type of prefix character to be used before
                        each list item:
                          order - Ordered list. Prefix character is
                            a number or a letter, depending on
                            style
                          bullet - Unordered list. Prefix character
                            is a bullet, dash, or other symbol
                          alpha-lower - Ordered list. Prefix
                             character is a lowercase alphabetical
                             character
                          alpha-upper - Ordered list. Prefix
                             character is an uppercase alphabetical
                             character
                          roman-lower  - Ordered list. Prefix
                             character is a lowercase roman
                             numeral
                          roman-upper  - Ordered list. Prefix
                             character is an uppercase roman
                             numeral
                          simple - Simple or plain list (no prefix
                              character)
             prefix-word
                        Holds a word, such as "Step" or "Process"
                        that is to be added to each item of a list.
                        The word is in addition to any prefix
                        characters such as numbers or bullets,
                        and typically follows the prefix character.
                        For example, A list type of "1" and a
                        prefix word of "Step", would produce:
                        "Step 1. ssss", "Step 2. ssss", etc.
                        Note that the word is "Step" and not "Step ".
                        The odd man out is the unordered list,
                        type "2", which is the only case in which
                        the prefix character would precede the
                        prefix word: - Step   - Step, but the
                        combination is not usually sensible.
             list-content
                        There are some list models in use in journal
                        DTDs, where a specific named list has been
                        created instead of using <list> or <def-list>.
                        The "list content" attribute should be used
                        to preserve the semantic information
                        concerning such lists types.  Potential
                        values include: "procedure", "where-list"
                        (used in equations), "synonymy",
                        "compound-info", "algorithm", "notation",
                        etc. For example, if a list were tagged as
                              <procedure>
                              <list-item>...</list-item>
                              </procedure>
                        that tagging could be preserved as:
                              <list list-content="procedure">
                              <list-item>...</list-item>

             list-type  List prefix types.  Type describes the
                        type of prefix character to be used before
                        each list item:
                          order - Ordered list. Prefix character is
                            a number or a letter, depending on
                            style
                          bullet - Unordered list. Prefix character
                            is a bullet, dash, or other symbol
                          alpha-lower - Ordered list. Prefix
                             character is a lowercase alphabetical
                             character
                          alpha-upper - Ordered list. Prefix
                             character is an uppercase alphabetical
                             character
                          roman-lower  - Ordered list. Prefix
                             character is a lowercase roman
                             numeral
                          roman-upper  - Ordered list. Prefix
                             character is an uppercase roman
                             numeral
                          simple - simple or plain list (no prefix
                              character)
             prefix-word
                        Holds a word, such as "Step" or "Process"
                        that is to be added to each item of a list.
                        The word is in addition to any prefix
                        characters such as numbers or bullets,
                        and typically follows the prefix character.
                        For example, a list type of "1" and a
                        prefix word of "Step", would produce:
                        "Step 1. aaaa", "Step 2. bbbb", etc.
                        Note that the word is "Step" and not "Step ".
                        The odd man out is the unordered list,
                        type "2", which is the only case in which
                        the prefix character would precede the
                        prefix word: - Step   - Step, but the
                        combination is not usually sensible.
             list-content
                        There are some list models in use in journal
                        DTDs, where a specific named list has been
                        created instead of using <list> or <def-list>.
                        The "list content" attribute should be used
                        to preserve the semantic information
                        concerning such lists types.  Potential
                        values include: "procedure", "where-list"
                        (used in equations), "synonymy",
                        "compound-info", "algorithm", "notation",
                        etc. For example, if a list were tagged as
                              <procedure>
                              <list-item>...</list-item>
                              </procedure>
                        that tagging could be preserved as:
                             <list list-content="procedure">
                              <list-item>...</list-item>
                              </list>                              -->
