BUILDING BLOCK - Lexical Scope

Description	Abstract Concept A Lexical Scope is a kind of Abstract Entity Element that defines the existence, visibility, and accessibility of the entities nested within it through a Nesting Relationship. Nested Entity Elements have no independent identity or validity outside the lexical or structural scope in which they are defined - they exist only within and for the duration of their parent construct. Every Entity Element belongs to exactly one Lexical Scope. A Lexical Scope carries no intrinsic semantic meaning; it serves purely as a syntactic mechanism for establishing hierarchical containment. Examples: 1) Composite structures nesting their internal constituents. 2) Social structures nesting their roles and functions. 3) Computer functions nesting their local variables or inner functions 4) Packages nesting their building blocks.

Relationship	Cardinality	Target Entity	Source Entity	Description
Nesting Relationship	[*..0]	Entity Element	Lexical Scope	A Nesting Relationship is a Relationship Element that references its target Entity Element by nesting, using Nesting Adjacency.Nesting is a fundamental concept in complex systems organization where elements are contained within other elements, creating hierarchical or web-like structures. This embedding mechanism intrinsically links the properties, behaviors, and lifecycles of nested elements to their containing elements, forming cohesive units at multiple scales.Nesting facilitates the emergence of complex aggregates and properties from simpler entities, enables efficient design of systems across levels, and supports both autonomy and integration within systems (see Compositionality).Nesting also facilitates the creation of modules through packaging of building blocks (see Packaging).
Referencing Relationship	[*..0]	Entity Element	Entity Element	A Referencing Relationship is a Relationship Element that points at its target Entity Element through Reference Adjacency.
Dependency Relationship	[1..1]	Entity Element	Entity Element	A Dependency Relationship is a Relationship Element that specifies the existential dependency of the sourceRelationship Element on its target Relationship Element.The cardinality to the target Entity Element is [1..1].
Non-Dependency Relationship	[*..0]	Entity Element	Entity Element	A Non-Dependency Relationship is a Relationship Element that specifies that the existence the source Entity Element doesnt depend on the existence of its target Entity Element.The cardinality to the target Entity Element is [0..*].
