Marcin,

"I am a student from Poland. I have a big problem. I need for my testing 
large MathML documents, but it have to be embadded parts in XHTML or HTML 
files. Does anyone know where can I get examples of it?"

See 3.1.2 Using XHTML with other namespaces (http://www.w3.org/TR/xhtml1/#docconf).

This is not a Strictly Conforming XHTML 1.0 Document. XML DTDs do not provide
an explicit support for XML Namespaces (which followed XML 1.0). 

If you want conformance, you can:

(1) Make DTDs Namespaces aware using parameter entity tricks; 

(2) Use MathML 2.0 as a Module based on Modularization of XHTML (this is a
    transition to XHTML 1.1); 

(3) Wait for a MathML 2.0 XML Schema to appear. (Well, you can write one.)
