Why would this be informative? It seems quite possible to construct 
interop problems stemming from different implementations here e.g. a 
site that assumes that there will never be <script> elements in pasted 
text, or a site that assumes it can get scripts in the result of 
getData("text/html"). Therefore the exact behaviour of the platform in 
this respect needs to be normatively defined.
