This reveals a problem in the specification. The specification says in the text: (1) An atom is either a ·normal character·, (or other options that aren't relevant here) (2) A normal character is any XML character that is not a metacharacter. (3) A metacharacter is either ., \, ?, *, +, {, } (, ), [ or ]. This would imply that the character "{" cannot be used without escaping, making the above regex invalid. However, the grammar has: [10] Char ::= [^.\?*+()|#x5B#x5D] which permits "{" and "}" without escaping, making the above regex valid. 13293 1 mike 2006-12-31 18:35:43 +0000 (Note that the English text and the grammar also disagree about whether "|" is a normal character or a metacharacter). 20679 2 mike 2008-06-21 13:15:03 +0000 Bug #5778 has been raised against the spec on this point. 31229 3 ht 2010-01-26 11:27:13 +0000 *** This bug has been marked as a duplicate of bug 4015 ***
