A block definition diagram is based on the UML class diagram, with restrictions and extensions as defined by SysML. ...
Block and ValueType Definitions
A SysML Block defines a collection of features to describe a system or other element of interest. A SysML ValueType
defines values that may be used within a model. SysML blocks are based on UML classes, as extended by UML composite structures. SysML value types are based on UML data types. Diagram extensions for SysML blocks and value types are described by other subheadings of this sub clause." [www.omg.org/spec/SysML/1.3/PDF]
