* This is one of the core items in signature generation since it may need to do * all the "heavy" work, such as calculating digests and obtaining time-stamp tokens. *
* Classes or instances of {@code PropertyDataObjectGenerator} for properties that * are not supported by the library have to be registered through the {@code withPropertyDataObjectGenerator} * method in a {@link XadesSigningProfile}. The library includes default implementations * for all the supported properties but these may be overriden. *
* The classes that implement this interface may have dependencies on other library
* components (and also external components configured in the signing profile).
* To that end, the constructors and/or setters should use the {@code Inject} annotation
* from Guice.
