Randall,

Can you elaborate on this?  Should query parameters always
be separated by '&amp;' or ';' rather than '&'?

Should=20
<img src=3D"http://a.b.c/d?e=3D1&f=3D2&g=3D3">
<a href=3D"http://a.b.c/d?e=3D1&f=3D2&g=3D3">misc</a>
<form action=3D"http://a.b.c/d?e=3D1&f=3D2&g=3D3">...</form>

be changed to
<img src=3D"http://a.b.c/d?e=3D1&amp;f=3D2&amp;g=3D3">
<a href=3D"http://a.b.c/d?e=3D1&amp;f=3D2&amp;g=3D3">misc</a>
<form action=3D"http://a.b.c/d?e=3D1&amp;f=3D2&amp;g=3D3">...</form>

Do you also have any references on this?  So far I have found this:

http://www.w3.org/TR/1998/REC-html40-19980424/appendix/notes.html#h-B.2.2

which states:

  The URI that is constructed when a form is submitted may be used as
  an anchor-style link (e.g., the href attribute for the A element).=20
  Unfortunately, the use of the "&" character to separate form fields=20
  interacts with its use in SGML attribute values to delimit character=20
  entity references. For example, to use the URI "http://host/?x=3D1&y=3D2"=
=20
  as a linking URI, it must be written <A href=3D"http://host/?x=3D1&#38;y=
=3D2">
  or <A href=3D"http://host/?x=3D1&amp;y=3D2">.=20
=20=20
  We recommend that HTTP server implementors, and in particular, CGI=20
  implementors support the use of ";" in place of "&" to save authors=20
  the trouble of escaping "&" characters in this manner.=20
