Checking the capability of DRM separate delivery mime-type by the device issue.

Hi,

I try to check whether a device supports a DRM separate delivery mime-type or not. For this I am using the CDocumentHandler class for this purpose. It has a method "CanHandleL(TDataType aPrm)". So I am doing the following things to be sure whether a device is able to handle separate delivery.

//These are the mime-types which should be supported by the particular device to handle separate delivery content, I made the following arrangement only for showing the mime-checking things for which everyting is defined locally.

CDocumentHandler* iDocHandler = CDocumentHandler::NewL((CEikProcess*)iEikonEnv->Process());
CleanupStack::PushL(iDocHandler);

_LIT8( KMmsDrmContentCT, "application/vnd.oma.drm.content" ); // DRM Content
_LIT8( KMmsDrmRightsTFCT, "aapplication/vnd.oma.drm.rights+xml" ); // DRM Rights in textual format
_LIT8( KMmsDrmRightsBFCT, "application/vnd.oma.drm.rights+wbxml" ); // DRM Rights in binary format

TDataType dContent(KMmsDrmContentCT);
TDataType dRight(KMmsDrmRightsTFCT);
TDataType dRightBin(KMmsDrmRightsBFCT);

//Let me use CanHandle method checking each of these content types separately

//Fail reason defined in the DocumentHandler.h
//const TInt KMimeNotSupported = -12003; // No handler found

TBool handled = EFalse;

TRAP( err, handled = iDocHandler->CanHandleL( dContent));

if(handled)
{
//do something
//I get here for the device which does not support separate delivery
}

TRAP( err, handled = iDocHandler->CanHandleL( dRight ));

//I get KMimeNotSupported error for the device which actually supports DRM separate delivery

TRAP( err, handled = iDocHandler->CanHandleL( dRightBin ));
//Same goes here

CleanupStack::PopAndDestroy(iDocHandler);

//I used traping to override not showing the message by the CDocumentHandler class any warning

I suspect in case there is something to do with '+xml' thing, Should it be escaped? It should be handled by the CDocumentHandler class itself.

It would be great to know how to check the drm separate delivery mime types. I could check other mime types by the above mentioned ways though I did not check all.
