Not really, if you are referring to interpreting &sect in
&section=... as an entity reference for the section sign.
By SGML rules, a conforming browser recognizes &section as an entity 
reference, then checks for any definition for such an entity.

In this particular detail, using XHTML has actually a benefit: a validator 
will detect any attempt to use an entity reference without a trailing 
semicolon, and this helps to avoid some problems with current browsers.
