Detail Attributes are those that are bound to no geometry what so ever. It can be what ever type you want.

Variable mappings are saved in to a Detail Attribute.

There aren't any hard and fast rules to using attributes in general including detail attributes other than there are some nodes that require attributes to be named and typed correctly for them to work. That is all. It's node specific.

One interesting thing about Detail Attributes is that under some conditions, you can change a detail attribute without cooking the geometry.

I commonly use a detail attribute for the total area of a multi-primitive surface if I wanted to control the number of particles based on the incoming surface area. See the attached hip file.

birth_total_on_total_area.hip

There are a great many other uses for detail attributes and attributes in general. Look and learn from the hundreds of example files that ship with Houdini to see what attributes in general can do. That is one huge area where you go to learn Houdini as there is a wealth of knowledge in the networks and the comments on the nodes.
