You may be better off using DTML for text generation, although it is 
possible to use ZPT.

I don't understand this.

If the tal:condition evaluates false, the entire 'x' tag is omitted. 
Otherwise, the tag is replaced by the bgcolor_setting property.  I 
*think* you want:

tal:replace="python:test(path('here/ttw_style_editing|nothing'), 
template.bgcolor_setting, default)">#FFFFFF</x>

...which uses the property if 'here/ttw_style_editing' is true, and the 
default text '#FFFFFF' is the property is false or doesn't exist.

That what the "source" in "Browse HTML source" means -- TAL source code. 
  Unless they are accessing the template through a WebDAV source port, 
people pulling the .css should get the rendered text.

That's because ZPTs with a non-"text/html" content type use XML rules 
instead of HTML rules.  Your template then needs to be well-formed XML, 
and you must have expat installed.
