+Subject: [PATCH] docs: Fix template matching in page.xsl
+
+Our last default template had a match of "node()" which incidentally matched
+everything, including text nodes.  Since this has the same priority according to
+the XSLT spec, section 5.5:
+
+  https://www.w3.org/TR/1999/REC-xslt-19991116#conflict
+
+this is an error.  Also according to the same spec section, the XSLT processor
+may signal the error or pick the last rule.
+
+This was uncovered with libxslt 1.1.35 which contains the following commit:
+
+  https://gitlab.gnome.org/GNOME/libxslt/-/commit/b0074eeca3c6b21b4da14fdf712b853900c51635
+
+which makes the build fail with:
+
+  runtime error: file ../docs/page.xsl line 223 element element
+  xsl:element: The effective name '' is not a valid QName.
+
+because our last rule also matches text nodes and we are trying to extract the
+node name out of them.
+
+To fix this we change the match to "*" which only matches elements and not all
+the nodes, and to avoid any possible errors with different XSLT processors we
+also bump the priority of the match="text()" rule a little higher, just in case
+someone needs to use an XSLT processor that chooses signalling the error instead
+of the optional recovery.
