[xml/sgml-pkgs] Bug#519826: xmlroff: compat stylesheet does not handle RDF gracefully

[brian m. carlson]

Package: xmlroff
Version: 0.6.2-1
Severity: normal
Tags: patch

When I try to transform an XSL-FO file containing RDF metadata, xmlroff
complains:

   lakeview ok % xmlroff cn.fo                                          
   runtime error: file cn.fo line 197 element attribute
   xsl:attribute: The QName 'rdf:about' has no namespace binding in scope in the stylesheet; this is an error, since the namespace was not specified by the instruction itself.
   
   (xmlroff:23701): libfo-CRITICAL **: fo_xml_doc_set_base: assertion `fo_xml_doc != NULL' failed
   
   (xmlroff:23701): libfo-WARNING **: FoXsltTransformer error:: XSLT transform failed

The RDF metadata is embedded with a fo:declarations block so that fop
can pick it up and generate proper metadata (XMP and /Info) for the PDF.
The XSL-FO input file is the cn.fo.bz2 file from #519825.

It appears that this is due to using xsl:attribute and xsl:value-of to
copy an attribute instead of using xsl:copy-of.  I've attached a patch
to fix two of those places.  One of them is unlikely to cause any
problems because it only works on attributes with known-names;
nevertheless, using xsl:copy-of is more idiomatic, so I've fixed it.
