* 1. During construction all services and references are provided
* with the Saxon data binding, which is the one required by the
* XQueryInvoker
*
* 2. During startup:
* - a proxy is created for each reference and it is kept in the referenceProxies
* map, which is used later by the invoker to configure the Saxon parser;
* - each property value is read and put into the properties map. This is
* again used by the invoker to configure the Saxon parser
