Standard Clearance Format
There is the standard clearance format:
Authorisation to operate = "Cleared to"
Clearance Limit = usually the destination aerodrome
Route = description of the route to be followed
Level = the cleared level
and then there are the diversionary climbs, intermediate levels, reporting instructions, frequency change instructions etc added on - about 12 different elements if I remember rightly.
It would be logical to follow this format when issuing all clearances ie
"Turn Right Heading 235, Climb to FL50, Maintain 210kts, Report Passing 3000ft"
