RE: Setting the namespace in a document root element

As it happens this came up in another thread yesterday. The simple answer is
to use literal result elements rather than xsl:element. LRE's copy all
in-scope namespaces from the stylesheet (unless excluded using
exclude-result-prefixes), xsl:element doesn't. In any case, LRE's in my view
are easier to write and easier to read.

So change:

<xsl:element name="MD_Metadata" >

to:

<MD_Metadata xmlns:gco="http://www.isotc211.org/2005/gco">

This then raises the question of why your <xsl:namespace> instruction didn't
do the trick. It ought to, and the output I get from Saxon 8.8 in fact
matches your desired output.
