fn-type Type of Footnote

Type of information conveyed in the footnote (for example, contributor’s current affiliation, financial disclosure statement, reprint information).


There are many reasons why the text or metadata of an article might be footnoted. Where those reasons are known (for example, one of the reasons listed in the reasons values list below), this attribute can preserve that information. This could be a means of preserving, for example, that a contributor is on a leave of absence.
In this Tag Set, the @fn-type has a fixed list of values. Many JATS users find a restricted list useful for quality checking. But new situations for footnoting arrive that are not covered by this list, and there is an attribute to handle them.

Custom attribute value escape hatch

When a JATS tagger needs to record a value that is not a named value on the list, they should use the value “custom”. This tells a JATS processor that this footnote is not one of the known types. The attribute @custom-type should then be used to record the type of footnote.
For any <fn> with a @fn-type attribute that takes the value “custom”, then the @custom-type attribute must be used and must have a value. Schematron or similar can be used to enforce this and, if desired, to constrain the @custom-type values.
