The className input to ExecuteDTL is the full package and class name of a
standard DTL class. className must be prefixed with either the configured
standard DTL package name or the configured custom package name.
Otherwise ExecuteDTL throws an error.
ExecuteDTL looks to see if the corresponding custom DTL class exists,
and executes the custom class if found, otherwise executes the standard
product DTL. If neither is found, then ExecuteDTL throws an error.
ExecuteDTL calls the Transform method in that DTL class.
ExecuteDTL passes the input source and aux values unchanged to Transform.
ExecuteStandardClass provides a simple means for invoking the standard product
version of a transformation class from the customized version of that product
class. This method facilitates implementing customizations simply as post-
processors or pre-processors. This method depends on transformation config
definitions established in the local namespace.
This method will NOT work with the FHIR DSTU2 transform classes that are
located in the HS.FHIR.DTL.FromSDA and HS.FHIR.DTL.ToSDA packages. It will
work with the newer transform classes.
