The use of < isn't compatible with our existing format. We could use
But I don't see any advantage in that actually. I do see two drawbacks:
* It makes the parser for the common case more complex (1)
* It becomes rather unreadable when you need to have more information than
just a simple type. E.g. imagine you have an enumeration and want to specify
all possible values as well. And what about descriptions?
(1) The meta-information (type-information) is a reflection of the
applications internals, as such it is of no value to the application itself:
it's the application that has determined that a certain key needs to be an
integer in the range 1 to 5, the meta-information is there to communicate
that design aspect to users (2) and more generic config management tools.
(2) Those users that are interested in this kind of stuff and bother to read
their config files.
