Well, the problem may occur that an automatic code generation will cause multiple instances.
The code generation has to be changed if multiple instances are not allowed.

But I think it is a fundamental question that should be clarified.

Well as it is valid and logical to have  aria-labelledby="id1 id2", I
suppose concatenating them when multiple attributes are specified is  the
reasonable solution.

Subject: Question about multiple instances for ARIA relationships

All,

the question came up if multiple instances of aria-describedby and
aria-labelledby are perfectly allowed for a DOM node, and what UA should do
here (concatenate, only take the first ref etc.).

e.g.

<span aria-labelledby ="ID1" aria-labelledby ="ID2" />
<span aria-describedby="ID3" aria-describedby="ID4" />

Are the specs here unambiguous?

Best Regards
Stefan
