SYSMLR — SysML diagrams show only SysML-stereotyped elements

As discussed in the SysML 1.4 RTF meeting today, it is currently unclear whether all of the elements shown in SysML diagrams have a SysML stereotype applied or not.

In some cases, there is an explicit mention about the meaning of SysML diagrams, e.g., 11.3.1.1 Activity:

Activities in block definition diagrams appear as regular blocks, except the «activity» keyword may be used to indicate the Block stereotype is applied to an activity, as shown in Figure 11.1.

We need a clarification whether the meaning of SysML diagrams is that they show only SysML-stereotyped elements or not and if not which UML elements can be shown on a SysML diagram without any SysML stereotype applied.

No Change Required.

There are many UML elements that are reused in SysML that do not have a SysML stereotype applied. The elements that can appear on SysML diagrams are identified in the diagram element tables and the diagram extensions sections of each specification chapter. Any additional general clarification required should be added to Section 6.3 Conventions and Typography. However, no additional clarification is required at this time.
