[Bug 25185] Usage absorption can take crawling expressions when TDU derives from xs:anyAtomicType

actually, under current streamability rules, that would not be streamable,
because of the addition of fn:data() and the crawling posture of //title. If
you were to rewrite it as string(zero-or-one(//title)) it would work.
