RE: What is the DOM4 Attr interface used for?

Sebastian,

 

Thanks for the further clarification. One last question, I hope …

 

If the living standard supersedes level 4 then where does it tell me that? If I go to your general standards page (https://www.w3.org/TR/#tr_DOM) I see nothing that tells me that the DOM specifications have been superseded. There is no reference to the living standard. And, on the living standards page (https://dom.spec.whatwg.org/) there is no reference to it superseding level 4.

 

As a potential user and developer I need to be able to determine, unambiguously, and easily, what the latest, current standard is.

 

Regards,

 

Roy

Anne,

Many thanks for your response.

While I understand how the situation arose, it still doesn't solve the problem of the level 4 specification. As it stands at the moment, the "Attr" interface is not included either directly or indirectly in the "Element" interface. Consequently, elements have no attributes. So it is effectively impossible to implement.

 

That assumption is incorrect. The 'Element' interface has the 'attributes' property, which returns the DOM Level 3 'NamedNodeMap' (as you've already recognized).
 

I can see that the "NamedNodeMap" interface is defined in the level 3 core, so cannot be changed without breaking level 3 and lower. Why don't you redefine it in Level 4 with the current definition from the living standard?

 

The living standard *is* the current specification, superseding Level 4.

Sebastian

 

Leaving the level 4 specification in its current state requires, at the very least, a red comment highlighting the problem to users.

Regards,

Roy

Hi Roy,

Welcome to the DOM community. These days we mostly hang out in https://github.com/whatwg/dom and https://wiki.whatwg.org/wiki/IRC.

It's unfortunately not very clear, but you want to study https://dom.spec.whatwg.org/ instead.

Correct.

It's not a correct name, but since it was only ever used by attributes, changing the type of the things it holds is actually possible. Having said that, we might have to change Attr objects back to being Attr node objects. It's a little up in the air.

You're correct that it's a little weird, but unfortunately we cannot right all wrongs, just a handful.

Kind regards,
