Depends how you look at it. ASN.1 has a long and relatively successful 
history of use directly in network protocol elements. XML has a (not 
quite so long) history as passive protocol _payload_, but it's use 
directly in network protocol elements is comparatively novel with 
XML-RPC or SOAP/WSDL/WS-CHOR or XMPP.

So who's proposing the change? Maybe the burden of proof lies with 
ASN.1's detractors?

Now you're just being silly.
