Tells the document that it is about to be rewritten. That is, a sequence of replace operations that form a semantic unit will be performed on this document. A specification of the nature of the operation sequence is given in form of the session type.
The document is considered being in rewrite mode as long as stopRewriteSession has not been called. @param sessionType the session type @return the started rewrite session @throws IllegalStateException in case there is already an active rewrite session
