I found two problems, I think, with the specification of the pattern
attribute.
1) The type of the 'value' attribute of pattern is 'anySimpleType.' [1]
Should it not be 'string'?
2) The definition of 'atom' in the BNF for regular expressions [2]
says
atom ::= Char | charClass | ( '(' regExp ')' )
'Char' says
Char ::= [^.\?*+()|#x5B#x5D]
Since '()' is included in 'Char', the status of these characters
is, strictly speaking, ambiguous w.r.t. parsing an atom.
