However, as per the current rules, e.g. `foo-` is valid too. IMHO it would make sense to tighten the requirement by disallowing trailing hyphens, thus making `foo-` invalid. 103466 1 mathias 2014-04-07 11:08:51 +0000 Similarly, how about disallowing consecutive hyphens? `foo----bar` is not really a nice element name. 103468 2 zcorpan 2014-04-07 12:02:03 +0000 Nah, it'd be nice if this test case was valid: <foo-- id="x"/> <script> x.innerHTML = "</foo--><!--"; // wut </script> (j/k) But it's not clear to me what the point is. We don't disallow data----="" either. 103469 3 mike 2014-04-07 12:04:31 +0000 I seem to remember Dimitri mentioning there's some library that's intentionally using custom element names with trailing hyphens. 103470 4 nikeiwe 2014-04-07 14:08:46 +0000 I completely agree with Mathias, trailing hyphen or consecutive could cause a lot of confusion in naming, would be great to have these rules landed. 103472 5 dglazkov 2014-04-07 15:32:44 +0000 (In reply to Mathias Bynens from comment #0) > Custom element names must contain a hyphen, so e.g. `foo` is invalid, but > `foo-bar` is valid. > > However, as per the current rules, e.g. `foo-` is valid too.

If it's just aesthetics, I would really like to avoid dictating such opinions in a spec. For example, I quite like http://charbelrami.github.io/math-elements/ and don't see anything wrong with it. 105060 6 dglazkov 2014-05-05 17:58:19 +0000 Assuming no changes are necessary to the spec. Please reopen if you feel otherwise.
