Comment in a Citation


Used to mark unstructured text within an otherwise element-structured bibliographic reference (<nlm-citation>). In an unstructured bibliographic reference, this text would merely be data characters and not marked with a tag at all.


<nlm-citation> Comment in a Citation is used to contain additional information about a citation that is not appropriate in any of the other, named, information types. For extensive examples of formatted <nlm-citation>s including use of <comment>s in <nlm-citation>s, see: Sample PubMed Central Citations. To see tagged versions of these example, see: Sample PubMed Central Citations - XML Tagged.

Because the model for <citation> is a loose model with data characters allowed everywhere, this element will rarely be needed in <citation>s. The Comment in a Citation element is used in <citation>s largely for the sake of conversion, to preserve unusual bits of semantic markup when translating from other DTDs. Typical comments might include:

 <comment>translated from Russian</comment>

Related Elements

Display Note: Comment in a Citations should appear inline with other reference elements. This is a very different rendering from that given the similar element Annotation in a Citation, which is typically a longer commentary concerning a citation that is rendered as a block element.
