from the specs:

http://w3c.org/TR/2004/REC-xml-20040204/#sec-common-syn

2.3 Common Syntactic Constructs
[Definition: A Name is a token beginning with a letter or one of a few
punctuation characters, and continuing with letters, digits, hyphens,
underscores, colons, or full stops, together known as name characters.]

Names beginning with the string "xml", or with any string which would
match (('X'|'x') ('M'|'m') ('L'|'l')), are reserved for standardization
in this or future versions of this specification.

...
[4]   	NameChar	   ::=   	Letter | Digit | '.' | '-' | '_' | ':' |
CombiningChar | Extender
[5]   	Name	   ::=   	(Letter | '_' | ':') (NameChar)*


IMHO, a full regexp to check attribute names is a little bit of
overkill; look for "B Character Classes" in the mentioned document to
see what I mean.

a regexp of the form (no production quality code, just a starting point!)
/([_:a-z][-_\.a-z0-9]*)/i
should be sufficient for most cases.

just my 2 cents
