-/* General
- *
- * Please refer to the libpkix Programmer's Guide for detailed information
- * about how to use the libpkix library. Certain key warnings and notices from
- * that document are repeated here for emphasis.
- *
- * All identifiers in this file (and all public identifiers defined in
- * libpkix) begin with "PKIX_". Private identifiers only intended for use
- * within the library begin with "pkix_".
- *
- * A function returns NULL upon success, and a PKIX_Error pointer upon failure.
- *
- * Unless otherwise noted, for all accessor (gettor) functions that return a
- * PKIX_PL_Object pointer, callers should assume that this pointer refers to a
- * shared object. Therefore, the caller should treat this shared object as
- * read-only and should not modify this shared object. When done using the
- * shared object, the caller should release the reference to the object by
- * using the PKIX_PL_Object_DecRef function.
- *
- * While a function is executing, if its arguments (or anything referred to by
- * its arguments) are modified, free'd, or destroyed, the function's behavior
- * is undefined.
- *

-
-/* PKIX_ProcessingParams
- *
- * PKIX_ProcessingParams are parameters used when validating or building a
- * chain of certificates. Using the parameters, the caller can specify several
- * things, including the various inputs to the PKIX chain validation
- * algorithm (such as trust anchors, initial policies, etc), any customized
- * functionality (such as CertChainCheckers, RevocationCheckers, CertStores),
- * and whether revocation checking should be disabled.
- *
- * Once the caller has created the ProcessingParams object, the caller then
- * passes it to PKIX_ValidateChain or PKIX_BuildChain, which uses it to call
- * the user's callback functions as needed during the validation or building
- * process.
- *
- * If a parameter is not set (or is set to NULL), it will be set to the
- * default value for that parameter. The default value for the Date parameter
- * is NULL, which indicates the current time when the path is validated. The
- * default for the remaining parameters is the least constrained.
