You can explicitly select a namespace (and exclude others) using
<dtml-with ... only>,
for example:

<dtml-with expr="REQUEST.form" only>
<form>
 <input .... value="&dtml.missing-foo;">
</form>
</dtml-with>

If you don't use the "only", this still enforces that the REQUEST.form
namespace is the first searched.
