XFORMS implementation ( Custom HTML Tags)

I am trying to make a custom HTML Tag Library using XHTML along the same lines as they have done for MathML.  This means that I want to add my own HTML tags, eg:

<myAddress:addressline type="US"> ... <myAddress:addressline>

I want to do this using the the following processing instractions declarations in Internet Explorer:

<object id="AddressProcessor" classid="CLSID:7D0ABA89-C5F0-8756-891A-456C4B648F56" width="0" height="0">
</object>
<?import namespace="myAddress" implementation="#AddressProcessor"?>

I want to create a COM/ActiveX object that is referenced by the classid above which  is invoked each time Internet Explorer encounters "myAddress".

My question is whether anyone knows exactly how Internet Explorer expects that COM object to be defined. How does Internet Explorer determine the method to call in the COM object?  Since I want to create an address that is rendered as HTML, does the COM method have to return a value or does it simply print to standard output? If anyone has done this please, let me know (a sample would be great).
