Uh, this doesn't make sense.

Who says? What do you have to support this? Most people
will access the DOM through whatever interface we define.

Yes, we have consensus on this. :)

If accessor functions are part of the API, then they should not
begin with '_'.

I'm not. I would prefer to see accessor functions for
DOM attributes that are a part of the API and whos names
don't begin with '_'s.

Whatever path we start down, it should begin with a draft
that documements the DOM mapping for Python.

Not if you go to accessor functions instead of attribute-based access.
In summary, I think using attribute-based access for the Python DOM
API would be a mistake because it will make efficient DOM implementations
harder than necessary to create. I'd prefer to see accessor functions used
to provide access to DOM attributes.
There has, however, been relatively lettle discussion on this.
I'm curious what opinions others have.
