Webel Parsing Analysis: While Associations may be collected as elicited members of a Snippet this can quickly lead to clutter in the /member list display. Often just collecting an end Property as member is sufficient.

Webel Parsing Analysis: While Generalizations may be collected as elicited members of a Snippet this can quickly lead to clutter in the /member list display.

Webel Parsing Analysis: An anonymous Element may be collected as a /member of a Snippet (it is not important whether collected elements list with a clear name under /member, only that they are traceably elicited).

Webel Parsing Analysis: The symbol for a Parsing Analysis Container MUST be able to OPTIONALLY display a list of names of elicited model elements (a.k.a. members)

Webel Parsing Analysis: The absolute basics of the process (SysMLv1.x form)

SysMLv1.x: Q: Why can't a Package with PackageImports be used as a Parsing Analysis text container? Why is the SysML1.6 ElementGroup (extended and customised as the Webel «snippet») far better suited for text-driven model element elicitation?

MagicDraw/Cameo: The apparent grouping of member elements under an ElementGroup node in the model tree can cause complications for searching and for the Cameo Collaborator exports.

Webel Parsing Analysis: If you wish to show a «snippet» comment symbol (with its body text) in a presentation diagram (that is NOT a «pa» diagram) remove the '/member' tagged value from display so the only visible tagged value is 'source'.

SysML Block Definition Diagram (BDD)

An ElementGroup comment symbol may appear on more than one diagram type and may collect different kinds of anchored annotatedElement members from more than diagram.

The grouping of member elements by an ElementGroup is denoted here "logical" in the sense that it does not "steal ownership" of member elements (as opposed to "physical" ownership of elements in the model)

The default display of all tagged values on the comment symbol for an ElementGroup can make diagrams cluttered, but you can extend it with a custom stereotype and customise the default visible tagged values.

Element groups can be members of other element groups, but this does not imply that members of the first are members of the second.

The elements in a group are identified by the modeler, as opposed to being the result of a query, as in views.

Element groups do not own their elements and thus an element can participate in an unlimited number of groups.

Grouped elements are the annotated elements of the comment to which the stereotype is applied. This has several implications:

Optionally, members of an element group can be ordered using its orderedMember property.

OMG Systems Modeling Language (SysML) 1.6

The criterion for membership in an element group is specified by the body of the comment the stereotype is applied to. By grouping elements, the modeler asserts that the criterion of the group applies to the member.
