[Bug 4378] error in K2-NodeTest-21


--- Comment #23 from Michael Kay <mike@saxonica.com> ---
We could introduce the idea of a binding to the context item having static
scope, but there's no such concept in the current spec. All the prose talks of
it being bound dynamically, reflecting the XSLT 1.0 history.

I think that making it a static error would be a fairly disruptive change, both
in terms of the effect on the spec, and in terms of backwards compatibility.
Making XPDY0002 into a type error is a much "gentler" change, because it's a
very small change to the spec, and because implementations have more
discretion, so they can make their own choices about how to manage the
backwards compatibility issue. In addition it works much better for XPath,
where it's the host language that knows whether or not a context item is
defined for the XPath expression.
