A top-level variable evaluates with every previously evaluated global
in scope, so referencing an earlier top-level param works, directly or
via call-template; same-name globals resolve by import precedence with
the last fold winning, so a later sibling import beats an earlier one;
the stylesheet fold uniformly favors later contributions, matching the
post-order precedence model; and the XPath compiler accepts NCName:*
name tests, matching any name in the prefix's namespace at the -0.25
default priority, so @ped:* outranks @*. Xalan baseline 144 -> 134
(variable 10 -> 5, conflictres 8 -> 5).
