Where to find dom js

[Ric 2000]

Hi all,

We use Version 5.4.6 of Tapestry.
The script select.js uses via require a library dom.js, and also zone.js
and events ja. The two latter ones are existing in modules/t5/core, but
dom.js I can't find in the tapestry-core sources.
Do you know where to find it?

Regards, Ric
