Hi,

Since parentheses may be used for grouping this is obviously allowed, 

/foo/bar[ ( fish or cow ) and dog ]

however am I correct in assuming that the following example supplied in the spec is not allowed according to the grammar?

(preceding::foo)[1]

I do understand what it means etc. I just can't work out how (Expr)Predicate is allowed. It's not allowed to have '(' or ')' ina Step either.

thanks,

James.
