Type definitions from ASN.1 are not processed and therefore checks e.g. on templates referencing these types cannot be performed. Add support based on e.g. pycrate, Titan, or other ASN.1 parser to expose the definitions to T3Q so they can be considered during the processing. Different options can be considered * Convert the type definitions to TTCN-3 and use them as input directly (filtering warnings for the type definitions as they are not to be considered), can be done once or on demand. * Expose definitions in another way and check against them once all other resolution has failed. The conversion is probably the most straightforward way, but it may come at the cost of processing time. Requires definitions to be converted more or less completely.
