Thanks.

I was thinking about this, does it require a schema-aware parser (say Saxon PE) ?

I would presume so.

Suppose I have 2 XML documents I want to compare (not diff, just give me yes/no are they equivalent).

This is pretty simple to do even with things like ignoring whitespace options etc.  Many tools out there, including one I wrote

( http://www.xmlsh.org/CommandXcmp)

Now here's the twist …

Suppose I want to compare for XSD  data model equivalence, not XDM  equivalence ?

Example.

<number>1.0</number>

vs.

<number>1</number>

Without type annotation these are different.
But if I declare the type for number to  be xs:double

they should compare equal.

The XPath 2.0 deep-equal() function appears to do what you want here: it compares the typed values of the elements rather than their string values.
