[whatwg] [html5] Pre-Last Call Comments

[Kristof Zelechovski]

The ActiveX components I use are proprietary non-standard technology.
Granted.  However, the interface to them, HTML, is standard and
non-proprietary.  Of course, one can use proprietary extensions like
namespaces and data sources as well, and sometimes it is necessary for
rendering and data management, but the classid attribute has not been the
case until (yesterday).  Valid code simply makes a better interface overall,
which means validating it makes sense.
Using IE magic comments causes the validator to skip not only the parts that
have been invalidated, such as the classid attribute, but also the parts
that would be valid otherwise.  If there is error in there, it will go
undetected, which is bad.
