[Zope] Acquisition problem.

[Star War]

I am just wondering where such an expression is
mentioned in the zope book. and PageTemplates is just
a folder instance. How does it store such path
information? REQUEST.set() is a python call, is this
expression,
'templates.common.content.gfx.gfx_Reports', a special
function?

If I have a string storing
'templates.common.content.gfx.gfx_Reports', how to
write the REQUEST.set() statement to get the same
result?

Thanks
