Wrap cross-reference content

Hello,

When exporting a structured document to markup, the content of cross-references is normally inserted directly after the xref element without any  markup. Is it possible to define a read/write rule to wrap the content of a cross-reference into an element, possibly the xref element itself?

For example, rather than ...

<xref format="Heading & Page" srcfile="sample.fm#CHDHFFJF"/>List of abbreviations on page 4

... I'd like to get

<xref format="Heading & Page" srcfile="sample.fm#CHDHFFJF">List of abbreviations on page 4</xref>

The only other way I can think of would be to nest the xref into another element in the first place, but I'd like to avoid this extra element.

Do you have any suggestions?

Thanks in advance,

Johannes
