Each association follows the pattern (LABEL . SUMMARIZE),
or (LABEL SUMMARIZE COLLECT) where
LABEL is a string used in #+COLUMNS definition describing the
summary type. It can contain any character but \"}\". It is
case-sensitive.
SUMMARIZE is a function called with two arguments. The first
argument is a non-empty list of values, as non-empty strings.
The second one is a format string or nil. It has to return
a string summarizing the list of values.
COLLECT is a function called with one argument, a property
name. It is called in the context of a headline and must
return the collected property, or the empty string. You can
use this to only collect a property if a related conditional
properties is set, e.g., to return VACATION_DAYS only if
CONFIRMED is true.
Note that the return value can become one value for an higher
order summary, so the function is expected to handle its own
output.
Types defined in this variable take precedence over those defined
in `org-columns-summary-types-default', which see."

`:indent'
When non-nil, indent each ITEM field according to its level.
`:match'
When set to a string, use this as a tags/property match filter.
