The group concept does not work as expected

[kristogar]

When a group A is subjected to a build rule R I expect that every step inside the group will be skipped if the rule evaluates to false. However if a step B in A is also subjected to another build rule S it was observed that step B gets executed (this leeds to problem because the variable that is used to evaluate S is calculated in one of the steps that is skipped because of rule R). There are two suggestions:
1. Make the group concept consistent in the sense that the group can be evaluated as an entitity such that if it is subjected to a build rule that all group element will not even be evaluated when the rule evaluates to false.
2. Make it possible to put any number of build rules as a condition on a step.

Looking at the xml of the bld file that shows this defect it is clear that to solve this issue it would require a serious redesign. I believe however that this would seriously improve the product.
