Yes, there is. RFC 2854 [1] defines the valid contents for text/html data as 
either HTML 4.01 or XHTML 1.0 complying with Appendix C. 

It also documents that text/html content generally contains 'invalid' 
content (per those specs), but it doesn't make it legal to send such content 
as text/html, just notes that users should follow Postel's Law. 

If you need more references, the W3C TAG's 'Authoritative Metadata' 
finding[2] basically says, among other things, that if you send me something 
marked as text/html, I must not interpret it as anything other than 
text/html as defined by spec; in particular, I must not interpret it as a 
XForms document, or a document with XML namespaces. 

The TAG Web Architecture document[3] also covers some of this, but not so 

So, no, you really can't legally send and interpret an XForms document sent 
as text/html without violating both the RFC that defines what text/html 
means and also a W3C finding that describes how the web works.
