Notes:The ServiceTypeName field in the temp-table / xml document
may contain a comma-delimited list of interface/class names.
In that case a single service instance will be registered
using multiple interfaces
Sample XML structure:
<ttServiceLoader xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<ttServiceLoaderRow>
<Order>1</Order>
<ServiceTypeName>Consultingwerk.Framework.IAuthenticationService</ServiceTypeName>
<ServiceClassName>Consultingwerk.SmartFramework.Authentication.AuthenticationService</ServiceClassName>
<Disabled>false</Disabled>
<RequiredDatabases></RequiredDatabases>
<LazyLoading>false</LazyLoading>
</ttServiceLoaderRow>
</ttServiceLoader>
Disabled and LazyLoading are optional flags
Supports custom log file messages using the "ServiceLoader:2"
("ServiceLoader") or "ServiceLoader:3" custom message sub system.
