SYSML17 — SysML 1.2 Issues: Default stereotype on unlabeled box is not always optimal

Page 36, 8.3.1.1 Default «block» stereotype on unlabeled box is not always optimal

Original Text

Default «block» stereotype on unlabeled box
If no stereotype keyword appears within a definition box on a block definition diagram (including any stereotype property compartments), then the definition is assumed to be a SysML block, exactly as if the «block» keyword had appeared before the name in the top compartment of the definition.

Comment

I question whether this is always desirable, e.g.,

1) if the diagram had the «functional hierarchy» diagram usage stereotype applied, wouldn’t the default be «activity»,

2) if the containing block is an activity block, wouldn’t «activity» be the right default

Type: Clarification/Fix

Add sentences that say: If the bdd diagram has a «diagram usage» specified (such as «functional hierarchy»), a different default (such as «activity») can be used.

If the bdd diagram is for an activity block, the default stereotype elements is «activity»
