What exactly would it return? What, for example, would it return for
xsd:string? If it's "string", doesn't the application already know this?
If it's something else, don't you need a Locale parameter as well?

It reads better:
if A contains B, then check C
contains is part of an assertion, check is a command. Compare:
String.startsWith
and
String.trim
