4.11.2 Diagram Frame
Some of the diagram types that are denoted in the upper left corner of a diagram
frame deviate in SysML from the UML identifiers ( Table 4.1 ). Note that I used the
UML identifiers for the diagrams in the UML chapter (Chapter 3) (e.g., class for a
class diagram and not bdd for a block definition diagram). In all other chapters,
however, I use the SysML convention.

The matrix and table notations don ??™ t belong to the normative part of the
SysML specifi cation (i.e., they are recommended) but are not mandatory in order
to be SysML-compliant. In SysML the model element and the element type are
denoted in addition to the diagram type and the diagram name. The syntax for a
full diagram header is as follows:
type [model element type] model element [diagram name]
For example,
bdd [package] system context [with information flow]
