You can select elements by their namespace URI, by using parenthesis before the element name, in which you write the namespace URI. For example:

{urn:xsd:$ahV10}AppHdr/{urn:xsd:$ahV10}From

I'm not sure if this is applicable on prefixed elements though. I know it works with default namespaces (xmlns="xs:anyURI", not xmlns:prefix="anyURI"), but never tryed it with prefixes.Btw, it's useless to have a prefix if it's going to change. Choose your prefixes wisely. As far as XSLT goes though, if you're making a stylesheet for handling data that's not yours, it is a good idea to know and use the above.
