Template:Citation/identifier/subst/doc

The Template:Citation/identifier/subst is a wp:subst-compatible subtemplate of Template:Citation/identifier, used in wp:CS2 citation style to display id codes for documents (doi, bibcode, PMID, etc.) or books (ISBN, ISSN, etc.). Because the CS2 citation templates are designed to store hidden span-tags and COinS metadata, then subst'ing of the original templates does not generate basic wikitext, but rather the encoded "&lt;span class=...>__&lt;/span>" and other internal tagged markup which is not found in basic hand-coded citations.

To use the template, put {subst:Citation/identifier/subst|identifier=xx|input1=...} wherever the template {Citation/identifier} would be used to generate a document-id link, such as:.
