            Bug ID: 24503
           Summary: Ambiguous rule #5 under Combined Posture definition
           Product: XPath / XQuery / XSLT
           Version: Last Call drafts
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XSLT 3.0

Under the definition of Combined Posture
(http://www.w3.org/TR/xslt-30/#dt-combined-posture), the fifth term reads:

"If one or more of the input postures is crawling and the remainder (if any)
are either striding or grounded, then the combined posture is crawling."

The ambiguity is with "either". To me, it can mean anyone of those:

a) either the remainder are all striding, or the remainder are all grounded
(excludes both)
b) any of the remainder can be either striding or grounded (includes both)

Obviously, for a choice operand group, the rule should be (b), because grounded
is not in the way of streamability here.
