Two typos in and a suggestion for the XML Proposal

In updating my parser to the XML Proposal of 8 December, I find that 
there seems to be two typos in the EBNF production rules:

1) The encoding declaration 

 [81] EncodingDecl ::= S 'encoding' Eq '"' EncName '"' | "'" EncName "'"

should have parentheses around the quoted names:

 [81'] EncodingDecl ::= S 'encoding' Eq ('"'EncName '"' | "'" EncName "'")

2) The version info production

 [25] VersionInfo ::= S 'version' 
                        Eq ('"VersionNum"' | "'VersionNum'")

Here VersionNum is a nonterminal, not a literal string, and I think
what was meant was 

 [25'] VersionInfo ::= S 'version' Eq 
                         ('"' VersionNum '"' | "'" VersionNum "'")

I also have one suggestion for improvement of the proposal. The notation 
type production is 

 [58]   NotationType ::= 'NOTATION' S '(' S? Name 
                                         (S? '|' Name)* S? ')' 

It allows for space before the the alternation '|' but not after. It
would be more symmetric to have 

 [58']   NotationType ::= 'NOTATION' S '(' S? Name 
                                         (S? '|' S? Name)* S? ')' 

as in the enumeration production. Comments?
