Issue 15875:  SysML Issue on Multiplicity of Use Case Communication Associations (sysml-rtf)
Source: Lockheed Martin (Mr. Michael Jesse Chonoles, michael_chonoles2(at)omg.org)
Nature: Uncategorized Issue
Severity: 
Summary: SysMl does not give any example of using multiplicity on the relationships between actors and use cases. This is part of UML as shown in Figure 16.11. 

Apparently, the "official" interpretation of SysML is that if there is no example, it is not part of SysML. This incompatibility means that standardize training, books, etc, on  Use Cases can not be applied to SysML. And the notation is of value.
