Re: XSLT 2.0 empty string

Michael wrote

  There's actually nothing specific to XSLT 2.0 here: these are all 1.0
  expressions where 2.0 gives the same result as 1.0

  As with XPath 1.0, when you compare a set of things to a single thing, the
  result is true if there is at least one match.

I think the point of the example was that the expectation was that the
variable didn't have a set (sequence) semantic but rather was a string
as if string($f) had been applied, due to the as attribute on the
xsl:variable (which is a 2.0 feature of course).

But I think it's true to say that as="xs:string" does _not_ force an
empty sequence to coerce to an empty string, isn't it?
