XPath 2.0 processors are quite likely to give you a warning when you write
"/..", or other "guaranteed empty" path expressions such as @text() or
@foo/@bar. Under strict static typing these are errors - they fall into the
same category as path expressions containing misspelt names such as
doc/chatper. XSLT 2.0 doesn't use strict static typing but processors can
still report warnings for any path expression that's statically known to be
empty.

It would be interesting, but there aren't enough hours in the day...
