It already says "[r]eturn the first element" ? which attribute gets  
checked first is irrelevant. If you search by attribute, I guess you  
need to carry out both searches, then combine the results, order by  
tree order, and return the first.

It means exactly what it says: conformant documents cannot use @name,  
but parsers must look in @name. They serve identical purposes, so  
there's no reason to allow both in a document, but parsers must  
support both for compatibility.
