Hi Bruce,
Not sure if "()" always indicates function call.
XPath 1.0 grammar says
PathExpr = FilterExpr | . . . [ignoring others like LocationPath for ]
FilterExpr = PrimaryExpr | FilterExpr Predicate
PrimaryExpr = '(' Expr ')' | . . . [others too in the list, ignoring
them for convenience]
Where Expr is an 'OrExpr', which can be another PathExpr.
See [19] in section 3.1 of Xpath 1.0 specification.[http://www.w3.org/TR/xpath]

Sorry for not being clear enough, but I had meant to ask "why are
patterns like (foo) or (/child::foo) considered invalid patterns as
per XSLT specification ?"
Curious as to whether this kind of a pattern breaks any semantics of XSLT .
rgds,
I'll let someone else step in to correct me if I get the language wrong, but:
/ or foo are nodes, while () indicates a function call. So
"count(current())" or "count(foo)" would both be valid, because the
current() in the first is a function, while the foo in the second is
just a node..
