Hi all. Found this site while searching for drawing libraries. I'm looking for a library that allows the following:

1) Ability to dynamically display shapes in a shape template that can then be dragged onto a designer sheet. An example would be a shape template called user that queries a database or LDAP server and dynamically builds the shapes based on the result set and allows these to be dragged to the designer

2) Ability to control the export of the developed diagram to XML for use in another application.

3) Ability to do this in a Visio style interface.

4) Control over each shapes customer properties and the ability to set them dynamically.

5) Ability to set a text editor component for editing a custom property. Example would be a custom property that when edited uses a 3rd party control to edit, validate and save the data back to the property.

Any help is greatly appreciated. I am working on developing a GUI interface that allows our business analysts to design applications; export those definitions as XML and use that XML to drive both business logic and navigation in a custom development framework.
