Re: [Phpwiki-talk] rss for RecentChanges

My opinion is that PhpWiki's RSS should follow these three XML 1.0 
recommendations (but I haven't yet checked whether it actually does or not)
.

1. RSS files are written in XML, so text/xml or application/xml should be 
used:

RFC 3023: XML Media Types <ftp://ftp.isi.edu/in-notes/rfc3023.txt>

2. It appears some RSS implementations omit the XML declaration line. I 
believe many XML readers will interpret this as incorrect XML.

XML Declaration: <http://www.w3.org/TR/REC-xml#dt-xmldecl>

3. The XML declaration line must indicate the character set in use when 
unicode or UTF-8 is NOT being used. For example here is a declaration for 
an XML document encoded with ISO-8859-1:

    <?xml version="1.0" encoding='ISO-8859-1"?>
