SharePoint query-language... completely undocumented....

When you convert a SharePoint list view (defined in CAML) to a XSLT Data View, Frontpage generates a query that looks like:

<udc:connectioninfo xmlns:udc="http://schemas.microsoft.com/data/udc" purpose="Query"> <udcs:location xmlns:udcs="http://schemas.microsoft.com/data/udc/soap">STSDataAdapter</udcs:location> <soap:body xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <dsp:queryrequest xmlns:dsp="http://schemas.microsoft.com/sharepoint/dsp"> <dsp:dsquery select="/list[@id='{B077D467-7540-4358-8835-9775A3BF17D4}']" resultcontent="Both" resultroot="Rows" resultrow="Row" columnmapping="Attribute"> <dsp:query querytype="DSPQ"> <dsp:fields> <dsp:allfields includehiddenfields="true"/> </dsp:fields> <dsp:orderby> <dsp:orderfield> <attribute name="Name"> <clientparametervalue name="dvt_sortfield"/> </attribute> <attribute name="Direction"> <clientparametervalue name="dvt_sortdir"/> </attribute> </dsp:orderfield> <dsp:orderfield name="ThreadID" type="xsd:string" direction="DESC"/> <dsp:orderfield name="Ordering" type="xsd:string" direction="ASC"/> </dsp:orderby> </dsp:query> </dsp:dsquery> </dsp:queryrequest> </soap:body> <soap:header xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <dsp:versions xmlns:dsp="http://schemas.microsoft.com/sharepoint/dsp"> <dsp:version>1.0</dsp:version> </dsp:versions> <dsp:request xmlns:dsp="http://schemas.microsoft.com/sharepoint/dsp" service="DspSts" document="content" method="query"> </dsp:request> </soap:header> <udc:clientparameterbindings> <udc:clientparameterbinding name="dvt_sortfield" location="Postback;Connection" item="dvt_sortfield"/> <udc:clientparameterbinding name="dvt_sortdir" location="Postback;Connection" item="dvt_sortdir" defaultvalue="Asc"/> </udc:clientparameterbindings> </udc:connectioninfo>

And the strange thing is that virtually NO information is available on the query syntax.Why o why are such large portions of SharePoint still undocumented?

If anyone has some pointers for me to documentation on this stuff, please let me know!!
