Remarks

Code groups are the building blocks of code access security policy. Each policy level consists of a root code group that can have child code groups. Each child code group can have their own child code groups; this behavior extends to any number of levels, forming a tree. Each code group has a membership condition that determines if a given assembly belongs to it based on the evidence for that assembly.

Only those code groups whose membership conditions match a given assembly's evidence will be applied. If a matching code group has child code groups, then those children whose membership conditions also match the supplied evidence will likewise be applied.
