Subject: smartxml: Getting rid of nodeMoved event in favor of `move` flag on nodeDetached... 
X-Git-Url: https://git.mdrn.pl/fnpeditor.git/commitdiff_plain/dec5a3d8b3a4cc70a9b2bc7bc1305ba0ae11a369?ds=sidebyside

smartxml: Getting rid of nodeMoved event in favor of `move` flag on nodeDetached/nodeAdded events

Moving nodes is now expressed in terms of detaching and adding events.

This simplifies implementation and api a little bit and makes it easier
for a client code to handle "move events".
