Hello

I am starting to play with the dlm file to create the layouts and layout-owners for putting up content.

I'm a little confused about the capabilities/workings of the dlm file and was wondering if anyone can advise me. I'm getting little response from SCT Support.

Say if I have 3 roles in my system that a user could have in any of the 7 combinations:

1 role1
2 role2
3 role3
4 role1 and role2
5 role1 and role3
6 role2 and role3
7 role1, role2 and role3

but I want a user to have one of only two layouts based on the following combinations of roles they may have:
1 role1
4 role1 and role2
(I would like both layouts to have a home page but a user to only see one homepage- ie get only one layout)

do I have to code up just 2 layout-fragments in dlm.xml for:

role1
role1 and role2

or many more for:

role1 and not role2
role1 and not role2 and not role3
role1 and not role2 and role3

role1 and role2 and role3
role1 and role2 but not role3

ie do you explicitly have to include all role combinations in your dlm:audience logic?

if so this would become quite complicated very quickly as roles increase. I have a feeling I maybe over complicating things but am finding the documentation a bit parse and getting odd behaviour when i try and experiment with the dlm file.

Thanks for any advice!
