           Summary: K2-SeqExprCast-207 should be an optional error
           Product: XML Query Test Suite
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XML Query Test Suite

K2-SeqExprCast-207 is "Construct an xs:anyURI from an invalid string." 
However, F&O 17.1.1 Casting from xs:string and xs:untypedAtomic is clear that:

  For xs:anyURI, the extent to which an implementation validates the
  lexical form of xs:anyURI is ·implementation dependent·.

It is also worth noting that in Schema 1.1 last call:

"The ·lexical space· of anyURI is finite-length character sequences."

This is probably because (as previously discussed) the specification of the
anyURI datatype in Scheme 1.0 was ambiguous, being a weird union of URIs after
escaping and URIs before escaping, which means you can't really ascribe any
meaning to them at all.
