MSIE still doesn't support XHTML correctly at its current version (it 
treats XHTML sent with the text/html MIME type as HTML, but doesn't 
understand the correct MIME type application/xhtml+xml nor does it 
actually run XHTML files through the XML filter - XHTML files which are 
not well-formed XML don't throw a parser error nor does it parse the 
&apos; entity in XHTML files) and also lacks a lot of support for CSS2. 
According to MS the MSIE will cease to exist as a standalone program in 
the near future anyway.

Neither Opera nor Mozilla support the entire CSS 2 standard. No browser 
that I know of correctly applies the XML MIME RFC, which demands that 
any unknown MIME type, registered or not, with the +xml suffix is to be 
treated as XML if the browser supports XML (application/x-foo+xml should 
be treated as application/xml, same for image/fancyxmlthingy+xml, etc).

Some projects tend to adopt a lot of standards over time (the guys at 
Mozilla should be mentioned here), but I know of none that supports 
every standard it should support.
