Hmm.  With this document:

<p tal:omit-tag="default">Foo</p>
<p tal:omit-tag="nothing">Bar</p>

The tag is omitted for the first <p> element, which tells me that
default evaluates to true, not false.  Can you point to the precise
location you found this mis-information?

Start with the method emitStartElement() in the module:

Zope 3:  zope.tal.talgenerator
Zope 2:  TAL.TALGenerator
