Have a look at ICAO DOC 8168. There is a section that deals specifically with this.
When the hold is not based at a navaid i.e. it is at a VOR/DME fix etc there are very specific rules about making entries to the hold that are not exactly the same as the Sector 1,2,3 manoeuvres we use at a beacon.
Most if the info from the DOC is reproduced in the ATC section of the Jepps.
