Dear all/authors of ace-coap-est,

Section 5 of ace-coap-est-05 indicates URI discovery is possible to find the 
EST functions entry point URI. Also a well-known URI is defined:

coaps://www.example.com/.well-known/est/ArbitraryLabel/<short-est>.

This URI seems more complicated than needed? What if we simply define an 
always-available well-known URI, usable without any discovery:

coaps://www.example.com/.well-known/est/<short-est>

This re-uses the well-known EST namespace which is exactly defined to do EST 
functions. So using the short-est names within this namespace should be fine.
It is important that a well-known URI is available that is usable without 
discovery, just like EST RFC 7030 defines it for https.
The "ArbitraryLabel" only makes the URI longer.

best regards
Esko Dijk
