I found in following document:

following chapter:
6.14 Meta and Object Tag (2nd FP1)
The meta tag is used, for example, for controlling the cache. The supported meta attribute is http-equiv. Supported http-equiv directives are expires, pragma (for no-cache), and refresh.
The <object> tag is used to insert multimedia into a Web document.

Does that mean the Real Player could be embedded in a XHTML page ? Which classid have to be used? Where can I find a code snippet?

thanks a lot,
