Featrue request: Intellisense for custom tags

[am11]

Polymer, Knockout and many other HTML5 complaints front-end frameworks are engaged with this new thing called custom-tags (components-driven). Its basically about defining custom tags templates at client-end (as opposed to server-side "tag helpers", introduced in MVC6).

The HTML5 standard suggests that we need to have hyphenated name for our custom tags (say <pagination-tag data-id=".." per-page-"20" page-number="3"></pagination-tag> or <locale-transform culture="nl-NL">This text will be translated via an online translator tool.</locale-transform>).

Currently, there is no intellisense for custom tags and squiggly suggest that the tag is invalid. Although we can make intellisense custom-attribute-aware, but not the custom tag.

Please implement intellisense for client-side custom tags in HTML and Razor editors (and perhaps CSS editor too, for element selector? not sure), so to make it more familiar with HTML5 capabilities. I am not sure what would be the smartest course of action here: whether to have a white-list in WE's settings file or something more fancier like adding a template and calling it via <link rel="import" />, the polymer way?

Point to ponder: From intellisesne POV, would it be necessary to differentiate the client side custom tag with MVC6 TagHelper in Razor editor?

I don't know how this custom tags concept is so new to HTML5, it existed in HTML4 as well (via custom DTD I suppose?). I swear I saw custom tags back in 2004-05 in http://www.tek-tips.com/'s source.. But <link rel="import" /> thing is definitely quite a revolution. :)

@madskristensen, I know this should go to http://webessentials.uservoice.com/, but I am not sure if this is already possible, in development or under consideration.

This is on our backlog in the VS web team and we start working on it next week. I'm closing it here
