### 15.10.5 Omitting <xref> elements from footnotes

The way DITA handles footnotes results in footnotes with IDs not getting callouts unless an <xref> element is added to provide the callout. However, the DITA Open Toolkit is inconsistent on this point. The HTML transform wants the <xref> element, but the PDF2 transform does not.

To exclude <xref> elements from footnotes:

[DITAOptions]

; FootnoteXref = Yes (default, comply with spec) or No (indulge bug in

; DITA-OT for pdf2 output using Idiom/RenderX by omitting footnote

; xref)

FootnoteXref = No
