Package foo wants to add `face' stuff and package bar also wants to add
`face' stuff.  If both add it to the same piece of text, we have
a problem, and if they want to update it later they have to know who
"owns" the particular value (i.e. who it comes from) to know whether it
should be updated or not.

It never combines values of a single property, just overwrites an old
value with a new one.
