<input type="hidden"> works just fine with existing UAs even when one 
uses application/xhtml+xml provided that all meaningful whitespace has 
been converted to entities. 
 for LF, 
 for CR and so on. PHP, 
for example, provides function htmlentities() exactly for this purpose.

It would be nice to have a note about that somewhere in the spec. I too 
found it hard way.
