This requires indeed some official fixing since composing the URI from

     http://www.cidoc-crm.org/crm-concepts/ plus entity number
     e.g. http://www.cidoc-crm.org/crm-concepts/E22

was the advice given by ICS-FORTH at the time of delivering LIDO v1.0.
(and the LIDO spec follows it btw consistently, differences below seem 
to be due to word-wraps)

Please let us know if these are not valid anymore (which I wouldn't 
consider best practice..)
