EMBEDDED PDV Type

---

The ASN.1 EMBEDDED PDV type is a useful type used to include non-ASN.1 or other data within an ASN.1 encoded message. This type is described using the following ASN.1 SEQUENCE:

EmbeddedPDV ::= [UNIVERSAL 11] IMPLICIT SEQUENCE {

identification CHOICE {

syntaxes SEQUENCE {

abstract OBJECT IDENTIFIER,

transfer OBJECT IDENTIFIER

},

syntax OBJECT IDENTIFIER,

presentation-context-id INTEGER,

context-negotiation SEQUENCE {

presentation-context-id INTEGER,

transfer-syntax OBJECT IDENTIFIER

},

transfer-syntax OBJECT IDENTIFIER,

fixed NULL

},

data-value-descriptor ObjectDescriptor OPTIONAL,

data-value OCTET STRING

}( WITH COMPONENTS { ... , data-value-descriptor ABSENT})

The ASN1C compiler is used to create a meta-definition for this structure. This code will be always generated in the Asn1EmbeddedPDV.h and Asn1EmbeddedPDV.c/cpp files. The code will only be generated if the given ASN.1 source specification requires this definition. The resulting C structure is populated just like any other compiler-generated structure for working with ASN.1 data.

NOTE: It is recommended that if a specification contains multiple ASN.1 source files that reference EMBEDDED-PDV, all of these source files be compiled with a single ASN1C call in order to ensure that only a singled copy of the Asn1EmbeddedPDV source files are generated.
