Love it, especially point 3 which has now been adopted in the new AS4373 2007! Fancy that.
Here you go.

7.3.5 Remedial (restorative) pruning (H)
This type of pruning shall only be carried out on trees which have lost their natural form and structure through storm damage, mechanical damage, vandalism, lopping, dieback or disease. This method is usually only used when all other approaches have failed and replacing the tree is difficult. The purpose of this pruning is to prolong the useful life expectancy of such trees and to reduce their hazard potential.
This type of pruning removes damaged, diseased or lopped branches back to undamaged or healthy tissue. The final cut may not necessarily be at the branch collar. The aim is to induce the production of epicormic shoots from which a new crown is intended to be established. To achieve this, regrowth should be managed by reduction pruning or crown thinning.
NOTES:
1 This type of pruning should be done in several stages in an attempt to induce stable and successful regrowth.
2 Consideration should be given to removing dangerous trees.
3 Remedial pruning may create hazards from weak branch attachment. Trees should be carefully monitored.
