SysMLv1: TIP: You can strengthen the ill-defined semantics of Property 'aggregation' (an AggregationKind) by applying custom Stereotypes to a Property, documented with its intended use. Not perfect, but better than not. EXAMPLE: «assembled»
SysML: Syntax ain't Semantics: FUN CHALLENGE: SysMLv1 block property aggregation: 'The tornado chaser plane "has" a chaser car "with" a chaser team.'
UML2/SysML1.x: If AggregationKind 'shared' has meaning to you (and if you use it consistently without contradicting the use of 'composite' aggregation elsewhere in your model) by all means use it. Damn the purists! But it's going to die in SysMLv2 anyway.

A property typed by a SysML ValueType is classified as a value property, and always has composite aggregation. Source OMG Systems Modeling Language (SysML) 1.6
A property typed by a SysML Block that has composite aggregation is classified as a part property, except for the special case of a constraint property ... Source OMG Systems Modeling Language (SysML) 1.6
Constraint properties are further defined in Clause 10. A port is another category of property, as further defined in Section 9. Source OMG Systems Modeling Language (SysML) 1.6
A common interpretation of composite Aggregation of a part property in SysML domain modelling is that if the owner Block is "destroyed" so is the child part property. Webel adopts these semantics always.
FullPort::2_not_bound_to_fullport Binding connectors shall not link full ports (either directly or indirectly through other binding connectors) to other composite properties of the block owning the full port (or that blocks generalizations or specializati Source OMG Systems Modeling Language (SysML) 1.6
A FlowProperty need not have 'composite' AggregationKind, it can be 'shared' or 'none'. (The MagicDraw/Cameo default is 'none').
InterfaceBlock::2_no_part Interface blocks composite properties are either ports, value properties or flow properties. Source OMG Systems Modeling Language (SysML) 1.6
In an instance of Operating Car, which is one execution of it, instances of Brake Pressure and Modulation Frequency are linked to the execution instance when they are in the object nodes of the activity. Source OMG Systems Modeling Language (SysML) 1.6
Figure 11-14 shows a block definition diagram with composition associations between the activity in Figure 11-10 and the types the object nodes in that activity, with AdjunctProperty applied to the object node type end. Source OMG Systems Modeling Language (SysML) 1.6
Like all composition, if an instance of Operating Car is destroyed, terminating the execution, the executions it owns are also terminated. Source OMG Systems Modeling Language (SysML) 1.6
Each instance of Operating Car is an execution of that behavior. It owns the executions of the behaviors it invokes synchronously, such as Driving. Source OMG Systems Modeling Language (SysML) 1.6

The associations may be composition if the intention is to delete instances of the classifier flowing the activity when the activity is terminated. See example in 11.4, Usage Examples. Source OMG Systems Modeling Language (SysML) 1.6
When composition is used with activity blocks, the termination of execution of an activity on the whole end will terminate executions of activities on the part end of the links. Source OMG Systems Modeling Language (SysML) 1.6
Activities as blocks can have associations between each other, including composition associations. Composition means that destroying an instance at the whole end destroys instances at the part end. Source OMG Systems Modeling Language (SysML) 1.6
