I believe we should design this with multiple Ranges in mind. Otherwise 
multiple selection requires a lot of work in javascript. Even if we don't 
actually support multi-selection in V1, we should not block it for a future 
spec.

Subject: [Selection API] Plans regarding multiple ranges?

Hi all.

The current draft of the Selection API states:

    This specification follows non-Gecko engines in restricting
    selections to at most one range, but the API was still originally
    designed for selections with arbitrary numbers of ranges. This
    explains oddities like the coexistence of removeRange() and
    removeAllRanges(), and a getRangeAt() method that takes an integer
    argument that must always be zero.

If things change and multiple ranges are supported, there may (or may
not) be associated accessibility needs to address or techniques to create. If 
multiple ranges are not supported, then there are clearly not such needs or 
techniques. So before we (PFWG) give it more thought, do you happen to know 
what your plans are for multiple ranges? In particular, if some non-Gecko 
engine added support for multiple ranges, would your API change to reflect 
that? Or are the corner cases just too unpleasant?

Thanks in advance. Take care.
