Mike and David,

As always, thanks for your promptness and sound advice.

It was recently shown to me that (using a recent Saxon) this template

<xsl:template match="@schemaLocation"

does not match the @xsi:schemaLocation here:

<ead xmlns:xlink="http://www.w3.org/1999/xlink"

I am at a loss to explain this.

It took me a while too.

xpath-default-namespace sets the "default namespace for element and type
names". It doesn't affect attribute names. As in XML, unprefixed
attribute names are in no namespace, regardless of any default namespace.


But methinks this means, as respects attributes with namespace-qualified names, there is a hole, inasmuch as there is no way to address them without declaring prefixes for their names. (Effectively a residuum of the XSLT 1.0 situation.)

I understand that unprefixed attribute names are not in the default namespace (and understand why it would be bad if they were, and how this disjunction stems from the way the design of namespaces straddles syntax and model), so I guess it makes sense they can't be bound to a namespace at all ...

... but it does make for a gotcha. One more to file away (and I am not surprised it has to do with namespaces).

Thanks again,

Michael Kay Saxonica
