The attributes xml:lang, class, and id are universal attributes associated with every wml element. The Web browser supports these tags as follows:


Attribute	Support	Comments
xml:lang	No - will not be used	Currently only English is supported.
class	No - will not be used	Only half of the phone browsers support this attribute.
id	Yes - will be used
