IE9beta and XML

Hi,

I did a few XML related tests with IE9 beta yesterday, and found it 
behaves ... differently.

I'm posting this here to see whether other people see the same problems...

The good news: support for XHTML (with the proper media type) (I haven't 
tested the edge cases though).

The bad news: lots of XML content I have at 
<http://greenbytes.de/tech/webdav/> doesn't behave as it used to.

There seem to be several problems:

- the default stylesheet (creating the collapsible view) seems to be gone

- loading a very simple example from the local file system with XSLT-PI 
does not apply the XSLT on first load, but on reload (reproducible)

- XML with DOCTYPE seem to be a problem (MSXML6's ProhibitDTD property?)

- XSLTs with xslt:script seem to be a problem (in IE8 they would execute 
after a confirmation dialogue, in IE9 nothing seems to happen at all).

Are other people seeing these problems as well? (I tested on two 
machines running Win7 Ultimate 32bit).

Best regards, Julian
