Is the full answer that the HTML 4.01 spec says that href attribute takes a URI as an value and a URI is of type CDATA and that a user agent should replace character entities in CDATA sections? > > Martyn Shaw From comp.infosystems.www.authoring.html message by Jukka Korpela: http://groups.google.com/groups?q=group:comp.infosystems.www.authoring.html+ insubject:character+insubject:references+author:jukka&hl=en&lr=&safe=off&rnu m=1&seld=924924029&ic=1 [Subject: "Character references" explained; Date: 16/Feb/2001.] ... "On the other hand, especially when URLs with query parts, such as http://www.server.example/cgi-bin/x.pl?foo=bar©=42 occur in HTML documents, you need to take into account that an HTML parser (a correct one at least) will recognize anything that starts with & and a letter as an entity reference, even if it is not terminated by a semicolon. In the example case, © is taken as an entity reference that denotes © which in turn denotes the copyright sign, which is not allowed in a URL, but I digress. To prevent this, replace that & by & which is an entity reference that denotes & that denotes the & character as such (i.e. as not to be taken as a constituent of a character reference or an entity reference)."
