| 34 | <p>This special type is defined as a shorthand for the union of all known types in a TTCN-3 module. Known types include the following: built-in types, user-defined types, imported ASN.1 and other | |
| 35 | imported external types. | |
| 36 | <ul> | |
| 37 | <li>The fieldnames of the anytype shall be uniquely identified by the corresponding type names using the "dot" notation.</li> | |
