I don't think there is any way to allow a value in an enumerated list to
contain "@" - at least not with a DTD. You probably need to define the
value as something else, and then do a transformation every time you use the
value, i.e., instead of:
email ([EMAIL PROTECTED] | [EMAIL PROTECTED] ) #REQUIRED
do this:
email (name1_AT_abc.com | name2_AT_yahoo.com ) #REQUIRED
and then translate _AT_ to @ whenever you display or utilize a value.
Gruesome, I know.
Alternatively, use a CDATA attribute, and find some other mechanism of
validating the value and presenting the user with the list of choices.
