       "Subclasses of CIM_Credential define materials, information or "
       "other data which are used to establish identity. Generally, "
       "there may be some shared information, or credential material "
       "which is used to identify and authenticate an entity in the "
       "process of gaining access to, or permission to use, resources. "
       "Such credential material may be used to authenticate an "
       "entity's identity initially, as done by a "
       "CIM_AuthenticationService, and additionally on an ongoing "
       "basis (for example, during the course of a connection or other "
       "security association), as proof that each received message or "
       "communication came from a valid 'user' of that credential "
       "material.")]

          "The date and time when the credential was issued. Use a "
          "value of all '00000101000000.000000+000', (midnight, "
          "January 1, 1 BCE at coordinated universal time +0 minutes), "
          "if this information is not applicable. On CreateInstance, "
          "if this property is unspecified, or set to NULL, then "
          "current time is assumed.")]

      [Description (
          "The date and time when the credential expires (and is not "
          "appropriate for use for authentication/ authorization). If "
          "this information is not applicable, Use a value of "
          "'99991231235959.999999+999', (1 microsecond before "
          "midnight, December 31, 9999 CE, at coordinated universal "

          "to NULL, then a value of '99991231235959.999999+999' is "

          "expiration is set - but that there IS an expiration. The "
          "property may be set to either a specific date/time or an "
          "interval (calculated from the Issued datetime). For "
          "example, for Certificate Authority-signed public key, the "
          "expiration is determined by the CA. Another example is a "
          "voice mail password that expires 60 days after it is "
          "set/issued.")]
