Visual Studio client HTML Intellisense for WebForms server controls - html

Question

I want the same HTML Intellisense as for <a runat="server"></a> to also display for <asp:HyperLink runat="server"></asp:HyperLink> as well (client events, attributes, etc).
I already tried creating and adding this file to "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\Packages\schemas\html":

And adding xmlns:asp='http://schemas.microsoft.com/intellisense/html5/asp' to the <body></body> tag, but I only get the usual server side only Intellisense.
I actually want this for my custom server controls, but can get there on my own from here.
