Hi,

Yes, that's definitely something else that I'm checking out: Several
languages have abstracted ui widgets and interactions in platform
independent ways: Java, Smalltalk, Python and tcl/tk come to mind.  I can
imagine using one of these either directly, or more likely, basing an XML
language on a model that one of these languages have developed.  For
example, a piece of XML that uses the Java-style interaction model could
look like:

<UI>
    <BasicWidget id="1" x="100" y="100" height="50" width="50"
type="TextEntryField">
       <KeyPressListener name="2">
       <KeyPressListener name="3">
       <KeyPressListener name="4">
    </BasicWidget>
     etc...
