FWIW: in UDDI Version 2 the xml:lang attribute (where it occurred) was required (one missing was allowed), and required to be unique. In Version 3 this restriction was lifted - it was legal to have multiple occurrences of the same xml:lang in the one list - people produced some reasonable use cases.
Let's skip the mandatory and unique phase :-)

	Amy, I like the suggestion, I also think that making xml:lang mandatory
	and unique on repeated documentations would be overkill.
	I wonder though, for schema validation, do we actually need to allow
	extensibility attributes to allow xml:lang? I have a vague feeling that
	the xml: attributes are exempt from validation so they are allowed no
	matter what the schema says. I may be wrong, though, in which case
	adding the extensibility attributes on documentation would be good.
	Best regards,
