I'm using the following code in the init of a custom
client-side web component.

objWebService = document.createElement("div");
objWebService.style.display = "none";
objWebService.style.behavior = "/theDir/webservice.htc";
objWebService.id = "WebServiceObject";
parentElement.appendChild(objWebService);
objWebService.useService("/theDir/MCInterface.asmx?
WSDL","MCI");

This object must be created at runtime on the client
side.  The files exist and are reachable, it seems, but
when I run this code, it has a problem with the last line,
telling me that the "Object doesn't support this property
or method."  I assume it's taking about the useService()
method.

I've done some fiddling and I added <PUBLIC:ATTACH    
EVENT="onload" HANDLER="DoInit" /> to the webservice.htc
file.  I also tried this with oncontentready.

This code doesn't seem to be called.  I wrote a function
that displays the current code in a new window and the
object does show up in the document:

<DIV id=WebServiceObject style="DISPLAY: none;
BEHAVIOR: /theDir/webservice.htc"></DIV>

how do behaviors work when being added after the page is
finished loading?  Why isn't this working overall?
