The value of a custom metadata field that is named by the <meta-name> element
Some Tag Sets allow for metadata above and beyond that which is specified in this Tag Set. To capture this metadata during conversion, use the <custom-meta> element, which contains one name/value pair with few constraints on the length or content of the value. For example, if an element named <prev-journal-title> contains an older title for this journal, as part of the journal metadata, use the <custom-meta> element, with a <meta-name> of “prev-journal-title” and a <meta-value> containing the older name.
