But it doesn't allow the form prefix:deref(). (The prefix is needed, given that deref() belongs to the SML functions namespace.) Suggest to replace occurrences of 'deref(' with (NCName ':')? 'deref(' 15739 1 virginia.smith 2007-07-05 18:45:49 +0000 Decision is to fix in FPWD and Michael will open another issue to discuss whether to remove this BNF in favor of referencing the XPath spec and using prose. 15912 2 kumarp 2007-07-25 07:24:19 +0000 changed the BNF to: Selector ::= Path ( '|' Path)* Path ::= ('.//')?
