Explicitly mention dynamic navigation properties in [Core]

New wording in Section 3, Data Model, describing navigation properties:

Entities may have relationships to other entities, represented in entity types as navigation properties. Navigation properties are generally defined as part of an entity type, but may also appear on entity instances as undeclared dynamic navigation properties. Relationships may be addressed directly through a navigation link representing the relationship itself. Each relationship has a cardinality.

Taking out of proposed state.

We already agreed, in ODATA-74, to document support of open navigation properties, so I don't we don't need a proposal to add to OData Core; instead we need an issue to track any new semantics around open navigation properties (for example, optionally being able to specify the type/set of a navigation property, use of the URL for POST/PUT, or the use of open navigation properties in $filter or $expand.).

Keeping this issue open to track any proposed semantics around open navigation properties.
