Oh in that case you should be in good shape: you're not using xsl:copy-of
if it's called gml:X on the way in and <Point on the way out.

If you are not copying nodes from the source, the only other place
namespace nodes can come from is the stylesheet and
exclude-result-prefixes
should enable you to stop any unwanted namespace nodes coming from
stylesheet namespace declarations.
