SYSML16 — Arbitrary diagram linkage to model elements

Most modelling tools provide some means of connecting a model element to any of the diagrams in the model and then provide a means of (tool users) navigating through the linked diagrams by opening the linked diagrams directly from the nodes representing these model elements on a diagram. (The means for doing this is tool specific, although common conventions for following links exist in many GUI environments.) In general this is a very useful feature. Is it not time that the SysML standard acknowledged this and standardised it?
Two further considerations arise:
1. XMI support for denoting the model element diagram linkage, and
2. The standardised means of indicating that a diagram node has linked diagrams, perhaps by the adornment with a defined glyph in a specified location on the nodes shape.

Might be addressed by API in SysML20.

Needs to be traced to SysML20 and addressed there.
