Well, the vocabulary would probably be a "Browser Layers" vocabulary (listing
interface objects, not their names, since layers won't have human-readable
However, I don't see how that vocabulary would be necessary for the

up in a

find it just
fine by walking the code browser in APIDoc, as with any other interface or
Layer interfaces are just marker interfaces; if we'd treat every kind of marker

I don't feel strongly about this at all. It was mostly Steve's idea and I took
suggestion as it adds some conherence (IBrowserRequest, IBrowserResponse,
IBrowserLayerType, ...). It would be up to Steve to defend it, for all I care
we can use
the shorter forms.

Thanks, I guess this is a good use case. The good thing is that the whole
can be *optional*. The 'type' argument of browser:page et.al. won't require an
interface; any interface will do as long as it is or extends IBrowserRequest.
Only if you
want your layer interface to show up for TTW view registration, you'll need
that it shows up in the "Browser Layers" vocabulary and thus among the list of
That said, I still think that in the long term, local registration should not
be done TTW.
So this optional notion of ILayerType might not be necessary in the future
after all. For
filesystem-based development I don't find any compelling usage for it at all.
So, if there are no other comments on this proposal, I will update it with your
suggestions and get started on the implementation (on a branch, of course).
