 However, in the long run, Dia has dedicated UML formatting, and hence seems a more logical choice, although it is far less easy to use. So the maintained converter, at least for now, uses Dia files. However, in the long run, Dia has dedicated UML formatting, and hence seems a more logical choice, although it is far less easy to use.

 Since Dia includes dedicated UML widgets, these can be used to semantically extract them instead of relying on format limitations as was the case in the OOo converter test. Since Dia includes dedicated UML widgets, these can be used to semantically extract them instead of relying on format limitations as was the case in the OOo converter test.

 +The elements recognized are:
 +
 +  * "UML - State Term": used for initial and final states
 +  * "UML - State": used for other states
 +  * "UML - Transition": used for transitions. Properties include:
 +    * Trigger (event)
 +    * Guard (event outcome)
 +    * Action (post-state-switch behaviour)
 +
 +Other UML elements are available but not processed yet. The "UML - Fork" division/reunion bar could be the next addition, but state nesting is not being considered.
