"""
ASN.1 type classes for the time stamp protocol (TSP). Exports the following
items:

- TimeStampReq()
 - TimeStampResp()

Also adds TimeStampedData() support to asn1crypto.cms.ContentInfo(),
TimeStampedData() and TSTInfo() support to
asn1crypto.cms.EncapsulatedContentInfo() and some oids and value parsers to
asn1crypto.cms.CMSAttribute().

Other type classes are defined that help compose the types listed above.
