As many other pointed out, combination of Schematron + RELAX (or TREX or
whatever grammar-based language) is possible.
James showed a Schematron-driven combination, so I'll show RELAX-driven
You can add arbitary <assert> and <report> tag inside <elementRule>.
label 'XXX' always has 'xxx' as its tag name,
and it can only be appeared once.
<ref label="XXX" />
<ref label="YYY" />
<ref label="ZZZ" />
And these assertions are checked with every element that has label "foo".
Probably, you want to use RELAX's labels and roles within XPath
expression. I think that's what you wanted to do.
But IMO, such RELAX-customized (or TREX-customized or whatever) XPath is
a kind of overkill.
