SysML block definition diagram - Function Breakdown model

This example was drawn on the base of figure 1 on the webpage "Template: OASIS:FunctionalBreakdownStructure" from the OASIS website.
"The FunctionalBreakdownStructure template describes how to represent a relationship between a FunctionalElementDefinition and another FunctionalElementDefinition that is a constituent.
The SysML Block Definition diagram in Figure 1 shows how a functional breakdown is represented in the PLCS PSM."

"A block definition diagram is based on the UML class diagram, with restrictions and extensions as defined by SysML." [omg.org/ spec/ SysML/ 1.3/ PDF]

"In association football, the formation describes how the players in a team are positioned on the pitch. Different formations can be used depending on whether a team wishes to play more attacking or defensive football. ...
The 2–3–5 was originally known as the "Pyramid", with the numerical formation being referenced retrospectively. ...
For the first time, a balance between attacking and defending was reached. When defending, the two defenders (fullbacks), would watch out for the opponent's wingers (the outside players in the attacking line), while the midfielders (halfbacks) would watch for the other three forwards.
The centre halfback had a key role in both helping to organise the team's attack and marking the opponent's centre forward, supposedly one of their most dangerous players.
It was this formation which gave rise to the convention of shirt numbers." [Formation (association football). Wikipedia]
