I'm not from AIS, just a PPL who has been working with them on some of the problems.
Content of the E line is down to the originator of the NOTAM. AIS are not the originators, they just publish them. Nor are they policy making. That role is down to the CAA's Directorate of Airspace Policy. AIS is part of NATS, which is the agency CAA has licensed to provide the service. While AIS may suggest originators include the a/d name it won't go in there as of right unless CAA/DAP make a ruling to that effect. AIS also work to a set of policy rules known as OPADD (Operational Procedures for AIS Dynamic Data) OPADD is a European set of standards designed to comply with ICAO SARPS (Standards and Recommended Practices). As you will gather from all of this it is important that all AIS's adhere to common standards. Details of OPADD
here.
ICAO designators are preferred because they are unique while aerodrome names are not.
If you fly repetitive sectors try naming them using the Briefing ID, then you can pull them straight out of the Briefing Handbook and re-use them.
On the other hand if you work in a limited geographic area rather than the entire FIR then try defining a local area using the technique I've outlined earlier in this thread.
