CDA types: incorrect backbone elements processing.

[ryukzak]

Currently:

export interface SubstanceAdministration extends InfrastructureRoot {
    resourceType: "SubstanceAdministration";

    administrationUnitCode?: CE;
    approachSiteCode?: CD[];
    author?: Author[];
    classCode: ("FCNTRCT" | "COV" | "CNTRCT" | "CACT" | "ACTN" | "INFO" | "STC" | "CASE" | "OUTB" | "COND" | "OBSSER" | "OBSCOR" | "ROIBND" | "ROIOVL" | "OBS" | "ALRT" | "CLNTRL" | "CNOD" | "DGIMG" | "INVSTG" | "SPCOBS" | "SPLY" | "DIET" | "DOCCLIN" | "CDALVLONE" | "DOC" | "COMPOSITION" | "ENTRY" | "BATTERY" | "CLUSTER" | "EXTRACT" | "EHR" | "ORGANIZER" | "CATEGORY" | "DOCBODY" | "DOCSECT" | "TOPIC" | "FOLDER" | "ACT" | "ACCM" | "CONS" | "CTTEVENT" | "INC" | "INFRM" | "PCPR" | "REG" | "SPCTRT" | "ACCT" | "ACSN" | "ADJUD" | "CONTREG" | "DISPACT" | "ENC" | "INVE" | "LIST" | "MPROT" | "PROC" | "REV" | "SBADM" | "SUBST" | "TRNS" | "VERIF" | "XACT");
    _classCode?: Element;
    code?: CD;
    consumable: InfrastructureRoot;

Where consumable is too generic type:

export interface InfrastructureRoot extends ANY {
    resourceType: "Act" | "AssignedAuthor" | "AssignedCustodian" | "AssignedEntity" | "AssociatedEntity" | "Authenticator" | "Author" | "AuthoringDevice" | "Authorization" | "Birthplace" | "Component" | "ComponentOf" | "Consent" | "Criterion" | "Custodian" | "CustodianOrganization" | "DataEnterer" | "Device" | "DocumentationOf" | "EncompassingEncounter" | "Encounter" | "EncounterParticipant" | "Entity" | "Entry" | "EntryRelationship" | "ExternalAct" | "ExternalDocument" | "ExternalObservation" | "ExternalProcedure" | "Guardian" | "HealthCareFacility" | "Informant" | "InformationRecipient" | "InfrastructureRoot" | "InFulfillmentOf" | "InFulfillmentOf1" | "IntendedRecipient" | "LabeledDrug" | "LanguageCommunication" | "LegalAuthenticator" | "MaintainedEntity" | "ManufacturedProduct" | "Material" | "NonXMLBody" | "Observation" | "ObservationMedia" | "ObservationRange" | "Order" | "Organization" | "OrganizationPartOf" | "Organizer" | "OrganizerComponent" | "ParentDocument" | "Participant1" | "Participant2" | "ParticipantRole" | "Patient" | "PatientRole" | "Performer1" | "Performer2" | "Person" | "Place" | "PlayingEntity" | "Precondition" | "Precondition2" | "PreconditionBase" | "Procedure" | "RecordTarget" | "Reference" | "RegionOfInterest" | "RelatedDocument" | "RelatedEntity" | "RelatedSubject" | "Section" | "ServiceEvent" | "Specimen" | "SpecimenRole" | "StructuredBody" | "Subject" | "SubjectPerson" | "SubstanceAdministration" | "Supply";

    realmCode?: CS[];
    templateId?: II[];
    typeId?: II;
}

but it should be a backbone element with nested types:
