I read that as saying that the value of the attribute doesn't matter. In fact, the document says that "Boolean attributes may legally take a single value: the name of the attribute itself (e.g., selected="selected")." I believe this is the same in XHTML - so a literal value of "false" is invalid, and doesn't mean anything. However, it looks like browsers treat it as a true value. So <input selected="false"> and <input> are equivalent in neither spec nor practice :-/.
However, I'm somewhat less reluctant to break code that's invalid in the first place, and I would like the inverse of => true to work intuitively. I'll talk to Hampton about this. - Nathan Mislav Marohnić wrote: > Re: "Allow rendering of <input checked>-style attributes in HTML mode." > http://github.com/nex3/haml/commit/ae3c44f574f6ef842850ede446e48e4f7bac0191 > > %input{:selected => false} > > will render as: > > <input selected="false"> > > The docs say that this is not equivalent to not rendering an > attribute.
