[html401] control types

In  
<http://www.w3.org/TR/1999/REC-html401-19991224/interact/forms.html#input-control-types>  
it is unclear what happens when the specified value does not match any of  
the allowed value for the "type" attribute. Given what implementations do  
that should be "text". Please clarify the specification so that it is  
clear for implementors what they have to do when the value of the "type"  
attribute does not match any of the specified values.
