I love Schematron, and it satisfies most validation/constraint/rules
stories very well, but no so much the description/abstraction story.

I'd like to define a way XPath could be used to say
"here's a bag of values I'm sending / expect you to send".

WADL does this, but XPath is a little too powerful for a
declarative language.

Using the xsl:template/@matches or xs:keyref/xs:selector/@path
profile might do it ..

(Adding the XPath 2.0 QName / Regex / base-types processing
   maybe interesting, but going too far)
