Re: ISSUE 30 @longdesc use cases

OK, I hesitate to ask, point this out.  It is perhaps a minor point.

There is an assumption/assertion here that a long description is hugely relevant but only through accessibility provisions.  But there may easily be puzzled users who do not have vision issues.  There is nothing wrong with a page that says "A detailed description of this can be found _here_.", and indeed this will, in fact, benefit a number of users other than those using screen readers (users new to the subject, in some cases, for example).  Not using the attribute does not preclude you from building informatively constructed web sites, does it? I don't find "A detailed description of this can be found _here_." 'traumatic' or 'confusing', myself, in general.
