xref.with.number.and.title broken going from 1.75.2 to 1.76.0

I have a customisation of the DocBook stylesheets which sets

<xsl:param name="xref.with.number.and.title">0</xsl:param>

This was working with version 1.75.2 of the stylesheets. However, on
upgrading to 1.76.0 this no longer works. The numbers and the titles
are both output for references to tables, sections, equations etc.

Can anyone here help please?

Thank you.
