Modifying TXT records created by Service class is not possible!?

[petersmar]

When creating a new Service class the constructor will accept a properties parameter. The content is put into a TXT record associated to the SRV record.

But is there any way to modify this record after service is registered via Poco::DNSSD::DNSSDResponder::registerService? There is no Poco::DNSSD::RecordHandle returned that can be used to call Poco::DNSSD::DNSSDResponder::updateRecord.

I created a Service instance without passing properties parameters to the Ctor and added a Record afterwards via Poco::DNSSD::DNSSDResponder::addRecord. But the result is, that there is automatically created an empty TXT record when the service is registered. This Record is of type TXT and has a TXT length of zero.

Have a look at frame number 11. There you can see the two TXT records. On is the empty one that was created when the service was added.
