The wish list would also include looking at whether there are certain policies that are out of date and should be reviewed. There ought to be a process that recognizes major changes that would require a strategic environmental assessment.
You can do a strategic environmental assessment on a regional basis. If there is all of a sudden a lot of development in an area, that may warrant doing a strategic environmental assessment on a regional basis. If all of a sudden there is all kinds of economic activity in one area and you're concerned about competing uses, this could also trigger the need for a strategic environmental assessment.
My basic suggestion is that it should be discretionary in the first instance. You identify the opportunity and then you make someone responsible for considering whether a strategic environmental assessment is appropriate. If it is, then you go ahead with it.
