SYSML16 — Change keyword of binding connector from "equal" to "="

The keyword "equal" needs a lot of space in a diagram. It would be better to have shorter notation for binding connectors.

The proposal is to use the equal sign = instead of the keyword with guillements <<equal>>.

Proposal: Change keyword of binding connector from "equal" to "="

Add the equal sign = instead of the keyword <<equal>> as an additional alternate notation for binding connectors. Binding connectors are often used in internal block diagrams and the keyword <<equal>> clutters the diagram. The equal sign is much shorter and the meaning is commonly known.
