ISO 8879, RFC 1866, REC-html40

In particular, see the note in 8.2.1 of RFC 1866.

Consider:

<a href="http://example.com/ohms_law.cgi?ohm=2&amp=5";>

What is the actual value of the URI in the link?

Now consider:

<a href="http://example.com/ohms_law.cgi?ohm=2&amp;=5";>
<a href="http://example.com/ohms_law.cgi?ohm=2&amp;amp=5";>

Each is clear and unambiguous.

Those RFCs are about URIs, not about HTML.  When a URI is encoded in
HTML, HTML escaping rules must be used.  Do you also think that ' and "
should be allowed in href attributes without escaping?
