[VE][122] Smart quotes not allowed in the value of attribute "id"

I was validating the following XHTML 1.0 Strict fragment:

<h1 id="&#8220; &#8221;">header text</h1>

and got the error that the "smart" quotes were not allowed. I'm
curious as to why that is, since smart quotes are high-ASCII Unicode
characters like any other, and hex-encoded Chinese characters (e.g.
&#x884C;) are perfectly allowed in 'id' attribute values.

Please clarify,
Dan Dascalescu
