Hi Bob,

this should raise error as xmlns is not attribute in XPath data model.
Saxon throws the following message:

Recoverable error
at xsl:attribute on line 78 of
file:/e:/src/db/xsl/epub3/../template/titlepage.xsl:
  Invalid attribute name: xmlns

and xmlns is ignored. Of course this is little bit edge case so other
processors might give different results.

I have added ns parameter to titlepage.xsl. It has to be set for FO and
XHTML, but should be empty for HTML. I have used different means for
setting namespace, but result seems ok. I have modified Makefiles as
well. You can see it as revision 9112.

We should warn users in release notes that when generating custom
titlepage templates this additional parameter has to be set fo FO/XHTML.
