[whatwg] alternate ids for elements

[Julian Reschke]

Hi there,

I have a use case where a certain location in a document can have two 
anchors (or even more). For instance, in a spec, the author may have 
specified an anchor, but a section-number based anchor is required as well.

Right now I can address this by inserting an additional <div> element, 
but this is kind of ugly, and doesn't scale well.

How about a new attribute "alt-ids" which would take a space-separated 
list of additional anchors?

Best regards, Julian
