I am using XText in collabotration with other Eclipse EMF based projects
and I would like to integrate XText with graphic based editors in order to
define textual annotations for graphical elements. One of the feature I
would like to have from XText, is to be able to define areas inside of
XText Editor which are read only. These sections are suppose to be
automatically generated/maintained by other modules. How difficult is to
implement a such feature?
