+ <para>
+ This filter acts as a sink for
+ SRU GET/POST/SOAP explain requests, returning a static ZeeReX
+ Explain XML record from the config section. All other packages
+ are passed through, including SRU GET/POST/SOAP searchRetrieve
+ requests, which are handled by a following
+ <literal>sru_z3950</literal> filter.
+ See the
+ <ulink url="&url.zeerex.explain;">ZeeReX Explain</ulink>
+ standard pages and the
+ <ulink url="&url.sru.explain;">SRU Explain</ulink> pages
+ for more information on the correct explain syntax.
