P.S.: Sorry, I should have possibly suggested a fix (in case I am not mistaken
about the ambiguity). What I would suggest is modification of the rule for
FTWordsValue as follows:

FTWordsValue ::= Literal | ("words" "{" Expr "}")

The unhappy disadvantage of this is more verbose syntax of Full Text. The
advantage which IMO prevails is upward compatibility with XQuery in the example
above and similar.
