Processors
Interfaces, Classes, Traits and Enums
- AugmentParameters
 - Use the parameter->name as keyfield (parameter->parameter) when used as reusable component (openapi->components->parameters).
 - AugmentProperties
 - Use the property context to extract useful information and inject that into the annotation.
 - AugmentSchemas
 - Use the Schema context to extract useful information and inject that into the annotation.
 - BuildPaths
 - Build the openapi->paths using the detected @OA\PathItem and @OA\Operations (like @OA\Get, @OA\Post, etc).
 - CleanUnmerged
 - DocBlockDescriptions
 - This would be detected as summary.
 - ExpandClasses
 - Iterate over the chain of anchestors of a schema and: - merge anchestor annotations/methods/properties into the schema if the anchestor doesn't have a schema itself - inherit from the anchestor if it has a schema (allOf) and stop.
 - ExpandInterfaces
 - Look at all (direct) interfaces for a schema and: - merge interfaces annotations/methods into the schema if the interface does not have a schema itself - inherit from the interface if it has a schema (allOf).
 - ExpandTraits
 - Look at all (direct) traits for a schema and: - merge trait annotations/methods/properties into the schema if the trait does not have a schema itself - inherit from the trait if it has a schema (allOf).
 - InheritProperties
 - Copy the annotated properties from parent classes;.
 - InheritTraits
 - MergeIntoComponents
 - Merge reusable annotation into @OA\Schemas.
 - MergeIntoOpenApi
 - Merge all @OA\OpenApi annotations into one.
 - MergeJsonContent
 - Split JsonContent into Schema and MediaType.
 - MergeTraits
 - MergeXmlContent
 - Split XmlContent into Schema and MediaType.
 - OperationId
 - Generate the OperationId based on the context of the OpenApi annotation.
 - MergeTrait
 - Steps: 1. Determine direct parent / interfaces / traits 2. With each: - traverse up inheritance tree - inherit from first with schema; all other with scheme can be ignored - merge from all without schema => update all $ref that might reference a property merged.
