--- Comment #1 from Michael Kay <mike@saxonica.com> ---
I'm reluctant. Posture and sweep are internal properties of expressions and
there is no obligation on processors to expose them. A processor could
conceivably implement exactly the same streamability rules without using these
concepts, or could refine them, e.g. to a larger set of posture and sweep
values to capture extra distinctions. Processors are also allowed to provide
streaming of constructs that are not guaranteed streamable.
I think it should be possible to recast such tests in terms that are exposed by
the spec, e.g. if an expression is motionless then it can be used as a
predicate in a pattern; if the posture is striding then it can be used in the
select attribute of xsl:for-each.
