WS-Fragment Uncertainties in the specification

Hi,
I am working on diploma thesis guided by Rostislav Svoboda from Red Hat. 
Theme of the work is  to implement WS-Transfer specification for Apache 
CXF framework. After finishing the main part of WS-Transfer 
implementation, I have started to implement the WS-Fragment 
specification, because in the specification of the WS-Transfer it is 
written that the WS-Fragment must be supported. During the 
implementation I encountered with problems, which I discuss in document 
https://developer.jboss.org/docs/DOC-52941?uniqueTitle=false

Could you answer me to questions, which I ask in the document?

Thank you.

Cheers,
Erich Duda
