Elements with dashes (Web Components support)

[wimleers]

Over at https://www.drupal.org/node/1333730, we're working on pulling in masterminds/html5 via Composer into Drupal 8 core. But we're running into a problem: this library doesn't seem to support elements with dashes.

Elements with dashes are necessary for Web Components support (http://w3c.github.io/webcomponents/spec/custom/). However, technically, the Web Components spec is non-normative (http://www.w3.org/TR/html5/references.html#references), so it's not necessary — strictly speaking.

That being said, I think most people would argue Web Components are clearly going to become an important aspect of web development in the not-too-distant future, and hence we want to make sure Drupal 8 doesn't break them, and hence it'd necessary for this library not to break them, if Drupal 8 wants to use this library.

Would you be willing to add support for Web Components, and hence elements with dashes?

hi! strange... are you sure? I'm dashes should be allowed. do you have a failing test case?

well i''m sure. I did try to add some code here but never posted on github before so assumed that code-tags are allowed but it didn't work properly but read here for an example code: https://www.drupal.org/node/1333730#comment-9387707

The #66 is intended to fix this. I'm just waiting for a feedback from other collaborators.
