><P
> This function configures the CCL query parser for a target
with definitions of access points (CCL qualifiers) and their
mapping to RPN. To map a specific CCL query to RPN afterwards
call the <A
HREF="function.yaz-ccl-parse.html"
><B
CLASS="function"
>yaz_ccl_parse()</B
></A
> function.
Each index of the array <TT
CLASS="parameter"
><I
>config</I
></TT
> is the
name of a CCL field and the corresponding value holds a string
that specifies a mapping to RPN.
The mapping is a sequence of attribute-type, attribute-value
pairs. Attribute-type and attribute-value is separated by an equal
sign (<TT
CLASS="literal"
>=</TT
>). Each pair is separated by white space.
