*
*
* ISIS-MTT PROFILE: The relatively complex structure of AdmissionSyntax
* supports the following concepts and requirements:
*
* - External institutions (e.g. professional associations, chambers, unions,
* administrative bodies, companies, etc.), which are responsible for granting
* and verifying professional admissions, are indicated by means of the data
* field admissionAuthority. An admission authority is indicated by a
* GeneralName object. Here an X.501 directory name (distinguished name) can be
* indicated in the field directoryName, a URL address can be indicated in the
* field uniformResourceIdentifier, and an object identifier can be indicated in
* the field registeredId.
*
- The names of authorities which are responsible for the administration of
* title registers are indicated in the data field namingAuthority. The name of
* the authority can be identified by an object identifier in the field
* namingAuthorityId, by means of a text string in the field
* namingAuthorityText, by means of a URL address in the field
* namingAuthorityUrl, or by a combination of them. For example, the text string
* can contain the name of the authority, the country and the name of the title
* register. The URL-option refers to a web page which contains lists with
* �officially� registered professions (text and possibly OID) as well as
* further information on these professions. object identifiers for the
* component namingAuthorityId are grouped under the OID-branch
* id-isis-at-namingAuthorities and must be applied for.
*
- See
* http://www.teletrust.de/anwend.asp?Id=30200&Sprache=E_&HomePG=0 for
* an application form and http://www.teletrust.de/links.asp?id=30220,11
* for an overview of registered naming authorities.
*
- By means of the data type ProfessionInfo certain professions,
* specializations, disciplines, fields of activity, etc. are identified. A
* profession is represented by one or more text strings, resp. profession OIDs
* in the fields professionItems and professionOIDs and by a registration number
* in the field registrationNumber. An indication in text form must always be
* present, whereas the other indications are optional. The component
* addProfessionInfo may contain additional applicationspecific information in
* DER-encoded form.
*
*
* By means of different namingAuthority-OIDs or profession OIDs hierarchies of
* professions, specializations, disciplines, fields of activity, etc. can be
* expressed. The issuing admission authority should always be indicated (field
* admissionAuthority), whenever a registration number is presented. Still,
* information on admissions can be given without indicating an admission or a
* naming authority by the exclusive use of the component professionItems. In
* this case the certification authority is responsible for the verification of
* the admission information.
*
* This attribute is single-valued. Still, several admissions can be captured in
* the sequence structure of the component contentsOfAdmissions of
* AdmissionSyntax or in the component professionInfos of Admissions. The
* component admissionAuthority of AdmissionSyntax serves as default value for
* the component admissionAuthority of Admissions. Within the latter component
* the default value can be overwritten, in case that another authority is
* responsible. The component namingAuthority of Admissions serves as a default
* value for the component namingAuthority of ProfessionInfo. Within the latter
* component the default value can be overwritten, in case that another naming
* authority needs to be recorded.
*
* The length of the string objects is limited to 128 characters. It is
* recommended to indicate a namingAuthorityURL in all issued attribute
* certificates. If a namingAuthorityURL is indicated, the field professionItems
* of ProfessionInfo should contain only registered titles. If the field
* professionOIDs exists, it has to contain the OIDs of the professions listed
* in professionItems in the same order. In general, the field professionInfos
* should contain only one entry, unless the admissions that are to be listed
* are logically connected (e.g. they have been issued under the same admission
* number).
