#963 Xsl-ns, block d:comment, d:remark template does not match

[Alexey Elizarov]

An error found in fo/inline.xsl in the namespaced stylesheets. When examining the problem, the similar error was found in html/inline.xsl.

When trying to generate pdf from a docbook with a block-level <remark>, on the stage fo->pdf I get the error message:

>[error] Element 'fo:inline' cannot be a child of 'fo:flow'. Only block-level elements are permitted in this context.

The error is caused by incorrect entity definition in fo/inline.xsl ($Id: inline.xsl 7440 2007-09-12 17:30:52Z mzjn $):

<!DOCTYPE xsl:stylesheet [
<!ENTITY comment.block.parents "parent::answer|parent::appendix|...

which is further used in the template:

<xsl:template match="d:comment[&comment.block.parents;]|d:remark[&comment.block.parents;]">

The namespace d: is missing. This should be:

<!DOCTYPE xsl:stylesheet [
<!ENTITY comment.block.parents "parent::d:answer|parent::d:appendix|...

The same error is in the html/inilne.xsl ($Id: inline.xsl 7232 2007-08-11 16:10:40Z mzjn $).

Though, in the xhtml/inline.xsl (This file was created automatically by html2xhtml from the HTML stylesheets.
$Id: inline.xsl 7232 2007-08-11 16:10:40Z mzjn $) all is correct. There are no entities, and the template definition looks like this:

<xsl:template match="d:comment[parent::d:answer|parent::d:appendix|...

It might be better not to use entities, but use the xhtml definition. Copying this line from xhtml/inline.xsl to fo/inline.xsl fixes the problem. The html/inline.xsl should also be fixed.

Found in docbook-xsl-ns 1.73.2, also in the snapshot revision 7580, on 2007-12-07 at 0105 PST.

There was a bug in the Perl script that converts non-namespaced stylesheets to namespaced stylesheets. The problematic entity is called comment.block.parents, but in the script it was assumed that entity names consist of alphanumeric characters only.

Tested: xsl-ns. In my case the xsl-ns version now creates correct output for all 3 targets: fo, html, xhtml. The version without namespace is not tested, though, I don't expect it to fail.
