[Iptel] CPL language switch

Hi,
Section 5.3 on Language Switches in draft-ietf-iptel-cpl-06
states
     "If the caller specified the special language-range "*",
     it is ignored for the purposes of matching."

I would assume that the caller has no specific choices about
the language and he accepts any language. Hence a CPL switch
on language trying to match a particular language is redundant.
Can I take that the 'language' output matched successfully for
this case and proceed further ?

But the next line states
     "Languages with a "q" value of 0 are also ignored."

Here the ignored word confuses me. Is it that the language
with a q=0 is ignored and other languages are used for matching?

Can someone plz clarify the same with an example ?

Thanx in advance.
