That is an opening angle bracket, but it will cause problems for XHTML served as HTML (since <script> elements implicitly contain CDATA in HTML documents). > Many people now enclose script blocks in CDATA sections, > i.e. http://www.w3schools.com/xml/xml_cdata.asp > <![CDATA[ > <script language="javascript" type="text/javascript"> The script element should contain CDATA, it shouldn't me marked as CDATA itself - otherwise browsers (treating the XHTML as XHTML rather than broken HTML) will render the entire script element as text! You also need to take steps so that the CDATA isn't treated as JavaScript if the document is served as HTML. The XHTML spec has suggestions on dealing with this. I just avoid XHTML on the client side except in situations where it provides a real benefit (which, so far, with the content I write, has been never). > A better solution is to tell PHP to use XHTML compatible argmuent > separators The requirement is not restricted to XHTML, it applies to HTML too. > (it's actually a bug in PHP's default setting on some versions). On some versions? When did they fix it? Last time I looked at the bug I got the impression that the developers were convinced that generating correct HTML by default would break people's scripts. > You're not sending it what "normal" user agents would see Rejecting cookies isn't /that/ unusual. -- David Dorward http://dorward.me.uk
