Hi John.
I know there is a fallback solution, but as the ID is auto-generated
in my app and it does adhere to
the standard w3c (except for a single character) wouldnt it be nice to
atleast include the minimum
characters allowed in the spec. I read the w3c spec:
ID and NAME tokens must begin with a letter ([A-Za-z]) and may be
followed by any number of letters, digits ([0-9]), hyphens ("-"),
underscores ("_"), colons (":"), and periods (".").
as:
[A-Za-z][A-Za-Z0-9-_.:]*
as they define the definition of a letter to be [A-Za-z] ascii. Then,
if you use unicode letters, you should escape/use fallback.
Well - just my 2 cents...
Cheers, Lars Borup Jensen
