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

&quot;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.&quot;

The ambiguity is with &quot;either&quot;. 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.</thetext>

    <thetext>We discussed this in Prague, without notable success in finding an alternative formulation that was less ambiguous than the current wording (which the WG took to require interpretation (b)).

- and each of the remaining input postures is either ... ?

- and each of the others ... ?

- and none of the others is climbing or free-ranging 

We left this to the editor&apos;s discretion.</thetext>

    <thetext>I decided to go with &quot;each of the remainder (if any) is either X or Y&quot;.</thetext>
