#
# PKCS #11 attribute definitions.
#
# The architecture of PKCS #11 is heavily based on an n-level-deep
# object inheritance hierarcy.  Concrete object types inherit
# attribute definitions, default values, usage constraints etc from
# abstract types.  Fine if one happens to be writing in a language
# that supports this, but C doesn't, and C++ is an abomination.
#
# So we handle all this inheritance-related fun here, by specifying
# object types and attributes in a (relatively) readable way and using
# a Python script to translate from this into "descriptors" (read-only
# C tables) we can use to automate some of the most tedious attribute
# checking in the C code.
#
# A secondary goal is to provide enough of a machine-readable
# description of the PKCS #11 object hierarchy that we can use it to
# drive automated test scripts, but that's not implemented yet.
#
# The base language here is YAML, with a somewhat ad-hoc data layout
# on top of it.  The exact semantics are a bit of a moving target, but
# the overall layout is:
#
# - The top-level data object is a YAML sequence (indicated in YAML by
#   the leading "- " marker, converts to Python list).
#
# - Each entry in the sequence describes one object, represented as a
#   YAML mapping (converts to Python dict).  Each object description
#   has at least one required field ("name"), several optional fields,
#   and one or more attribute descriptions.
#
# - An attribute description is a YAML mapping (Python dict)
#   containing one or more fields describing the attribute.
#
# So the overall structure is a sequence of maps of maps.
#
# Attribute definitions within the hierarchy are combined, so that,
# eg, the "rsa_public_key" type inherits the CKA_CLASS definition from
# the the root object type, the CKA_KEY_TYPE definition from the "key"
# type, a value of CKO_PUBLIC_KEY for the CKA_CLASS from the
# "public_key" type, and provides its own value of CKK_RSA for the
# CKA_KEY_TYPE.
#
# No doubt the error checking in the Python script could become much
# more rigorous than it is now.
#
########################################################################
#
# Currently-defined object fields:
#
# - "name": String, required.  Name of this object class.  For
#   concrete object types, this controls the name of the corresponding
#   C descriptor.
#
# - "concrete": Boolean, optional, default false.  If true, this
#   object type should generate a C descriptor.
#
# - "superclass": String, optional but present for all but one type.
#   Contains name of parent type.
#
# New object fields may be defined at a later date as needed.
#
# Any entry in an object mapping whose key starts with "CKA_" is
# assumed to be an attribute description.
#
# Keys in an object mapping which do not start with CKA_ and are not
# known object fields should result in an error during parsing.
#
########################################################################
#
# Currently-defined attribute fields:
#
# - "type": a PKCS #11 type name (CK_*) or one of a few other types
#   described in the PKCS #11 specification: "rfc2279string",
#   "biginteger", or "bytearray".
#
# - "default": data-value (see below) to be used as default if neither
#    the application template nor the PKCS #11 software itself
#    supplies an explicit value.  As a special case, the null string
#    ("") means that the default value of the attribute is empty (this
#    is allowed for a few rfc2279string attributes such as CKA_LABEL).
#
# - "value": data-value (see below) for this field.  If the
#   application specifies a value for this attribute, it must match;
#   otherwise, behaves like default.  The special handling of the null
#   string ("") used with default does not apply here.
#
# - "footnotes": Sequence (Python list) of integers in the range 1-12.
#   If present, this indicates that the attribute's definition in the
#   PKCS #11 specification has been tagged with the listed footnote
#   numbers from the "common footnotes" in "Table 15" of the
#   specification.  These footnotes specify various constraints on the
#   attributes behavior, and the Python script translates them into
#   flags with more meaningful names, but since the specification
#   itself is written in terms of these silly footnote numbers, using
#   the footnote numbers in the YAML makes it easier to check the
#   attribute descriptions in the YAML against the specification.
#
# - "unimplemented": boolean, default false.  If true, the attribute
#   is known to be in the specification but is not (yet?) supported by
#   the Python script and the C code.  This flag is set on a small
#   number of relatively obscure attributes whose internal structure
#   makes them tedious to represent in the attribute database; this is
#   a placeholder for attributes which should be implemented
#   eventually but which were not deemed to be on the critical path.
#
# As with object mappings, attribute mappings with unrecognized keys
# should result in an error during parsing.
#
# "data-value" fields ("default" and "value") in an attribute can take
# one of several forms:
#
# - A string value naming a PKCS #11 constant (eg, CK_TRUE);
#
# - A sequence of eight bit unsigned numeric values (ie, bytes)
#   specifying a literal value; or
#
# - An integer (Python long) specifying a numeric value for a
#   biginteger field, to be converted into a literal value using the
#   smallest possible number of bytes.
