+= Composable Custom Extensions Developement Plan =
+
+  This file captures the work items for the Composable Custom
+  Extensions Task Group in a work breakdown structure (WBS) [1].
+
+  [1] https://en.wikipedia.org/wiki/Work_breakdown_structure
+
+  Tasks must follow the principles of a WBS:
+
+  - Any, and varying, levels of hierarchy are allowed.  Only leaf
+    elements in the hierarchy represent work to be done.  Thus, only
+    leaf elements have time estimates, dependencies, owners, etc.,
+    assigned to them.
+
+  - Every task is only captured in a single place; nothing is duplicated.
+
+  - Non-leaf elements can be considered as the sum of all leaf items
+    with respect to time estimates, dependencies, etc.
+
+  - Time estimates are three point estimates (optimistic, expected,
+    and pessimistic).
+
+  This file is intended to be machine readable with ad-hoc tooling.
+
+  Time estimates are work time; scheduling will be done separately.
+  For estimating purposes, one day (1d) is eight hours (8h), one week
+  (1w) is five days, and one month (1m) is thirty days.
