There are some "Ambiguous rule match" warnings when running dblatex 0.3.5 with saxon-6-5-5.
Introducing 'priority="2"' in xsl/common/labels.xsl at the concerned templates is a crude work around.
- Ambiguous rule match for /article[1]/section[3]/section[3]
Matches both "part|chapter|appendix|sect1|sect2|sect3|sect4|sect5|section" on line 1055 of file:dblatex-0.3.5/xsl/xref.xsl
and "section" on line 231 of file:dblatex-0.3.5/xsl/common/labels.xsl
- Ambiguous rule match for /article[1]/section[3]/section[4]/section[1]/figure[1]
Matches both "figure|example|table|equation" on line 1061 of file:dblatex-0.3.5/xsl/xref.xsl
and "figure|table|example" on line 632 of file:dblatex-0.3.5/xsl/common/labels.xsl
There may be futher such problems, which are not triggered by my docbook document.
Thanks for the feedback. It should be fixed in release 0.3.6.
