I read the message and I don't see how it has anything to do with  
what I said. Please keep in mind that browser-hosted implementations  
allow dynamic creation of elements and insertion in possibly foreign  
namespaces. document.createElementNS("http://www.w3.org/1999/xhtml",  
"input") can only have one result, and it can't decide based on an an  
attribute on the root element what it's going to do because you could  
be calling it on a document where HTML is not even the root language.  
Identifying some notion of "document type" does not help with this  

In general, people commenting on what is or isn't doable in browsers  
may wish to consider studying some browser code first. There are two  
first-class open source browser engines available for you to read:


It's also easy to find experts on these code bases who are often glad  
to answer questions for standards experts about how things work.
