<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. &#10; for LF, &#13; 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.
