It is not correct to characterize all or even most content that needs > isolation (and/or auto-direction) as "user-provided" or as the "output of a > calculation" or in any way associated with forms (which the output element > seems to be). For example, let's say I am just authoring a simple HTML document > in an RTL language, and want to list a few of my favorite bands, e.g. "I LIKE > a, b, AND c." If I do not use isolation on a, b, and c, this will be displayed > as: > > .c DNA ,a, b EKIL I > > instead of the intended > > .c DNA ,b ,a EKIL I > > This can be solved by using ‏ ("a‏, b‏, AND c"), but this is ugly > and has other problems. > > What I really want to do is bidi-isolate each of a, b, and c even though they > are not user-provided or calculated, and I have no form in my page. > > For a different example take a web app, e.g. a search app. None of the things > that need isolation in each search result - the title, the snippet, the > filename, the size - is generated by the app's user, and there is no > association with a form. In a sense, they are calculated, but not in the way > intended for the output element. > > In brief, I do not think that the output element is a good fit for most use > cases - although having isolation on for output element by default (in addition > to a more general solution) is probably a good idea. > > 2. It is quite a common occurrence that the item needing isolation is already > wrapped in an element like <a> or <q> or <span> (or <output>). In fact, if <a> > and <q> were being invented today, we would want isolation for them by default > - but we dare not do that now because it would most certainly break some > existing documents. But having to wrap such items in *two* elements, e.g. > <a><ubi>BLAH BLAH</ubi></a> - or is it <ubi><a>BLAH BLAH></a></ubi>, is surely > rubbing salt in the wounds. An attribute with a short name and no need to > specify a value is a lot less painless to use. > > 3. As far as I understand, adding an "auto" value to the CSS direction property > is a non-starter. Fantasai should be able to provide more details. For this > reason, I am also reopening bug 10808. > > > Let's deal with the auto-direction issue separately in bug 10808, which I am > re-opening for reasons described there. > > Basically, you are saying that isolation will be provided by the <output> > element. Sorry, I had intended to delete the last two paragraphs of this comment ("Let's deal ..." and "Basically..."); please disregard them. -- Configure bugmail: http://www.w3.org/Bugs/Public/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
