Yes. In this case CONTEXT-ELEMENT should be "HTML" and TOP-ELEMENT  
should be "BODY". Body is inside HTML. But because you don't actually  
have the "BODY" tag in your file you need an empty HAS-SEEN-ELEMENT  
list. Some thing like this:

    ("mydecl.html" "HTML" "BODY" ())


That said, I am doubt that mmm-mode will work in this case. PSGML  
tries to parse the whole buffer, and unless mmm-mode actually manages  
to hide parts of the buffer from PSGML it will probably fail if there  
is anything outside the html fragments that makes the whole buffer  
invalid html.

In case of BODY it doesn't matter much because BODY is just a tag  
soup. But if, e.g., you wanted a file with the stuff the goes into  
HEAD, except for the title (it is specified some where else, say).  
Like <link>, <meta> etc. Only one TITLE is allowed in HEAD. If the  
parser had parsed one TITLE it wouldn't allow another one. In this  
case "TITLE" would be an HAS-SEEN-ELEMENT.
