I like the general idea, but I personally don't think axes are the way to go.
The main reason is that I would like such facilities to support general
"infoset" annotation, and not just WXS types. For example, this could be the
basis for generic dispatch of hyperlinks if the infoset-annotation to
reconciling XLink and HLink is chosen.
I would personally lean more towards:
match="child::*[annotation(., "dt:type") = "xsd:int"]
Though, I recognize that in my approach, one would have to write the full URI,
not just the QName "xsd:int".
