redeclare the same namespace prefix?

[KJ]

Is the following invalid:

<d:doc xmlns:d="http://whatever.com/ns">
<d:title xmlns:d="http://whatever.com/ns">
is this invalid?
</d:title>
</d:doc>

Thanks

It is well-formed XML with namespaces. The question of validity does not
arise unless you provide a schema.

I guess the general question is: is it legal to declare the same
namespace prefix pointing to the same namespace more than once, as
shown.

Yes it is.

Such a document conforms with <http://www.w3.org/TR/REC-xml-names/> so
it is "legal" as far as that specifcation defines what is "legal".

Got it, thanks.

In case anyone was wondering, the reason I was asking, is because
Visual Studio 2003 does not like it when elements redeclare namespaces.
