### 15.10.2 Specifying an outputclass for cross-reference wrappers

When Mif2Go encounters a cross reference, index marker, or footnote reference in a context where an <xref> tag would be invalid, the <xref> gets wrapped in a <ph> element. These Mif2Go-generated <ph> wrapper elements need an outputclass attribute. The default outputclass attribute names for cross-reference, index-term, and footnote wrappers are as follows:

[DITAOptions]

; XrefWrapClass = outputclass to use for generated ph elements that

; wrap xrefs where they would otherwise be invalid

XrefWrapClass = phxref

; IndexWrapClass = outputclass to use for generated ph elements that

; wrap indexterms where they would otherwise be invalid

IndexWrapClass = phindex

; FootnoteWrapClass = outputclass to use for generated ph elements

; that wrap footnotes where they would otherwise be invalid

FootnoteWrapClass = phfoot

You can specify other outputclass attribute names.
