UPDM — Section: 8.3.23

Description says there is a CustomView along with all the other Viewpoints, but it doesn't exist:
"The ArchitectureView is an abstract concept that groups the following kinds of views: o All View o Operational View o System View o Technical Standards View o Acquisition View o Strategic View o Custom View "

"An ArchitectureView is a ConformingElement and thus can be related to Standards. "
However, it extends Package, and ConformingElement extends class, so it can't be a ConformingElement.

"In some cases, it is desirable to assemble elements of the model and export them for processing by an external process; perhaps to produce custom presentations or to transform them into different forms. Using the UPDMAttributes, an external URI can be designated as the processing element, and the components within the View can be assembled as needed to complement the external process. "
"UPDMAttributes" should be "ExternalReferences"
