Schema for jPDL 4 process descriptions;
element process is the top level element.
TODO: Add activity pluggability. (add the proper any's and
anyAttributes)
TODO: Pull up expression. The expression element in the
delegation group can be pulled up as an expression
attribute in each use case of the delegationGroup
TODO: Investigate if object-refs to centrally defined objects would
add value over inline defined objects.
A jPDL process definition description; This
is the top level element in a jPDL process file.
The process name. Multiple processes can be deployed with the same name, as long as they have a different
version.
The key can be used to provide a short acronym that will replace the name as the basis for the generated
process definition id
Indicates the sequence number of this version for all processes with the same name. By specifying a version
automatic deployment can figure out if this process is already deployed or not.

java object is fetched from the environment. Then values from the
environment are injected into the fields and a method is executed.

Any java object that will be created by reflection. .
There are three main ways to create an object: by constructor or by a factory
object or a static factory method.
Using the constructor: Then the class attribute must provide the
fully qualified class name. In case another constructor then the default is
targetted, a constructor child element can be provided.
The factory attribute should not be provided for using a constructor.
Using a factory: Then the factory attribute or one
factory element must be provided along with the attribute
method.
Using a static factory method: Then the class and
method attributes should be specified. There should be no
reference to a factory attribute of element.
Construction and initialization: all objects (constructor and factory)
are build in two phases: construction and initialisation phase. During construction
all is done until a pointer is obtained to the object. In initialisation, operations
are applied to the object until it is ready to be used. The separation between
construction and initialisation is made to allow for bidirectional references. In
that case, at least one of both ends can not be fully initialised before it is injected
into the other end.
Operations: after construction, various operations can be applied to objects
like e.g. direct field injection, injection through setters, method invocation,
enlist with the standard transaction, subscribe the object as a listener to an observable
Arguments: There are two different places for arguments. The arg
elements for the factory method invocation should be placed as child elements under the
object element. The arg elements for the constructor should be
placed as child elements under the constructor element.
