Anything annotated must be able to construct the appropriate DFDLAnnotation object from the xml.

Here we establish an invariant which is that every annotatable schema component has, definitely, has an annotation object.
Here we establish an invariant which is that every annotatable schema component has, definitely, has an annotation object. It may have no properties on it, but it will be there. Hence, we can delegate various property-related attribute calculations to it.
To realize this, every concrete class must implement (or inherit) an implementation of emptyFormatFactory, which constructs an empty format annotation, and isMyFormatAnnotation which tests if an annotation is the corresponding kind.
Given that, formatAnnotation then either finds the right annotation, or constructs one, but our invariant is imposed. There *is* a formatAnnotation.
Define this for schema components that have back-references to ref objects.
Define this for schema components that have back-references to ref objects. So group def to group ref, globalelementdecl to element ref, type to element, base type to derived type.
Not for format annotations however. We don't backpoint those to other format annotations that ref them.

This avoids the need for the checking code to have a backpointer to the Term.

The enclosing component, and follows back-references from types to their elements, from globalElementDef to elementRefs, from simpleType defs to derived simpletype defs, from global group defs to group refs
The enclosing component, and follows back-references from types to their elements, from globalElementDef to elementRefs, from simpleType defs to derived simpletype defs, from global group defs to group refs
Note: the enclosing component of a global element or global group referenced from a element ref or group ref, is NOT the ref object, but the component that contains the ref object
All schema components except the root have an enclosing element.

If this is already an element, this still walks outward to find the next tier out.

Even if this is already a term, this walks outward to find those enclosing this.
Returns the group members that are elements or model groups.

Annotations can contain expressions, so we need to be able to compile them.

We need our own instance so that the expression compiler has this schema component as its context.
Namespace scope for resolving QNames.

We insist that the prefix "xsi" is properly defined for use in xsi:nil attributes, which is how we represent nilled elements when we convert to XML.
Used as factory for the XML Node with the right namespace and prefix etc.

Given "element" it creates <dfdl:element /> with the namespace definitions based on this schema component's corresponding XSD construct.
Makes sure to inherit the scope so we have all the namespace bindings.
Combine our statements with those of what we reference.
Combine our statements with those of what we reference. Elements reference types ElementRefs reference elements, etc.
The order here is important. The statements from type come first, then from declaration, then from reference.

For property combining only.
For property combining only. E.g., doesn't refer from an element to its complex type because we don't combine properties with that in DFDL v1.0. (I consider that a language design bug in DFDL v1.0, but that is the way it's defined.)
All non-terms get runtimeData from this definition.
All non-terms get runtimeData from this definition. All Terms which are elements and model-groups) override this.
The Term class has a generic termRuntimeData => TermRuntimeData function (useful since all Terms share things like having charset encoding) The Element classes all inherit an elementRuntimeData => ElementRuntimeData and the model groups all have modelGroupRuntimeData => ModelGroupRuntimeData.
There is also VariableRuntimeData and SchemaSetRuntimeData.
Elements only e.g., /foo/ex:bar

This is the root, or basic target namespace.
This is the root, or basic target namespace. Every schema component gets its target namespace from its xmlSchemaDocument.

Common concepts for components that define groups.
This includes both global group definitions, and local sequence and choice groups.
