The client page to be developed must include the evidence infrastructure page Evidence_createHeader.vim. This included.vim page facilitates the management of infrastructure attributes. For example, the Evidence Descriptor's receivedDate attribute is currently managed through this infrastructure page. If, at some point in the future, additional attributes which need to be managed through the create function were added to the Evidence Descriptor entity, then these attributes could be mapped through this infrastructure page. Hence, this requires just a once-off infrastructure change rather than many changes to custom artifacts.
