--- Comment #5 from C. M. Sperberg-McQueen <cmsmcq@blackmesatech.com> 2009-04-13 15:32:08 ---
Noah Mendelsohn has pointed out a flaw in the proposed wording, which
also applies to the description of the lexical space. ("The set of possibly
empty character sequences, huh? OK, here's a character sequence:
'http://www.w3.org/'. Could it possibly be empty? No, it's not empty,
and it couldn't possibly be empty without no longer being itself: I can
see characters right there. I guess it's not a member of the value space,
or of the lexical space either.")
Perhaps it would be better to change the proposed new section on value
space and the existing first sentence of the section on lexical mapping
from:
3.3.18.1 Value Space
The value space of anyURI is the set of possibly empty character
sequences.
3.3.18.2 Lexical Mapping
The ·lexical space· of anyURI is the set of possibly empty finite-length
character sequences.
to
3.3.18.1 Value Space
The value space of anyURI is the set of finite-length sequences
of zero or more characters.
3.3.18.2 Lexical Mapping
The ·lexical space· of anyURI is the set of finite-length sequences
of zero or more characters.
The proposed amendment is modeled on the formulation used to
describe the value space of string.
