Unlike Part 1 of XML Schema Part 2 is not unreadable, just go straight
to <http://www.w3.org/TR/2004/REC-xmlschema-2-20041028/#language>:
[...]
The ·lexical space· of language is the set of all strings that
conform to the pattern [a-zA-Z]{1,8}(-[a-zA-Z0-9]{1,8})*.
[...]
And the empty string does not match that pattern. I could not find a
public response that formally addresses either of
http://lists.w3.org/Archives/Member/w3c-xml-schema-ig/2004Jul/0057.html
http://lists.w3.org/Archives/Public/www-xml-schema-comments/2004JulSep/0086.html
so I don't know whether this is intentional though, maybe these comments
got "lost" somehow in the process. Let's hope such things don't happen
with comments on SVG 1.2... If normative corrections are published for
XML Schema that allow empty xs:language, that would of course address my
comment aswell.
