How to create customized UI for a UML profile ?

[Yehuda]

The objective is to set a designated properties dialog.
Just like when using XML Schema profile the properties window is customized (and the data is usualy kept in tagged values).
Is such functionality only enabled for Sparks and its partners?
if not - how can it be acheived ?

Thanks in advanced
Yehuda

You can intercept the double-click event and open your own properties dialog. Search the help for EA_OnContextItemDoubleClicked
