I bet that anyone who need to do more then one query would not like this
syntax. AFAIK MS API allows to bind namespaces to prefixes and use them
in XPath queries. So what is needed here is better education of
developers. And you can always stick to good old XPath way:

*[local-name() = 'myElement' and namespace-uri() =
'http://myDomain.co.uk/namespaces/ns1']

However it wouldn't be bad if some future version of XML (and XPath)
allowed to use Clarks notation everywhere where QName is allowed. But
this will hardly happen I think.
