eletrust.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). @see org.bouncycastle.asn1.isismtt.x509.Admissions @see org.bouncycastle.asn1.isismtt.x509.ProfessionInfo @see org.bouncycastle.asn1.isismtt.x509.NamingAuthority
