How do I remove a particular default xterm X11 translation?

I'm using xterm which comes with a set of default translations as enumerated in the man page. To #augment or #override the translations I edit my $XAPPLRESDIR/XTerm file; this works as expected.

However, I can't find a way ro remove a particular default translation (and have the event passed to the application running in xterm).

Specifically, I want the Meta <Btn2Down> event to be passed to the application. The xterm default translations bind this to the clear-saved-lines() action with

DEFAULT KEY BINDINGS

[...]

Meta <Btn2Down>:clear-saved-lines() \n\

What do I need to do for the application to receive the Meta-Btn2Down event?
