proposed change: links inside label elements

Currently the HTML spec allows links to be inside label elements [1]:

example:

<label for="test">
<a href="http://google.com">google</a></label>

<input id="test" type="checkbox">

This is problematic because the standard behaviour for a label that is
associated with a control is that when

clicked/pressed it activates the control (in the example case would
check/uncheck the checkbox), but when as in the example

the label includes a link, clicking /pressing the label activates the
link not the control.

I propose to change the spec to disallow links in labels (i.e. make it
an author conformance error).

current text:

Content model:Phrasing content, but with no descendant* labelable *elements
> [2] unless it is the element's labeled control, and no descendant labelelements.


proposed text:

Content model:Phrasing content, but with no descendant* interactive *elements
> [3] unless it is the element's labeled control, and no descendant labelelements.
