Re: FW: [XQuery] Pecularities in rules [143][144][145]

Hi Daniel.  Thank you for pointing this out.  The second set of characters 
was a production bug and does not have any special magical meaning.  The 
bug has been fixed.

FW: [XQuery] Pecularities in rules [143][144][145]






Hi,
another peculiarity strikes me. Have a look at these rules:
[143]    ElementContentChar    ::=    Char - [{}<&] - [{}<&] 
[144]    QuotAttrContentChar    ::=    Char - ["{}<&] - ["{}<&] 
[145]    AposAttrContentChar    ::=    Char - ['{}<&] - ['{}<&] 
According to section A.1 of XQuery 1.0 (23.07.2004)
A - B has the meaning of:
matches any string that matches A but does not match B
A look at [143] says that a character is an ElementContentChar, if it is a 
member of character class Char an it is not equal to any of the characters 
'{','}','<','&' and (a second time!!!) is not equal to any of the 
characters '{','}','<','&'
Is there a hidden meaning I do not catch? Or is it a typo? Or is the 
second set of characters plain redundant?
Cheers,
Daniel Kirmse
