+COMPATIBLE_INTERFACE_NUMBER_MIN
+-------------------------------
+
+Properties whose maximum value from the link interface will be used.
+
+The ``COMPATIBLE_INTERFACE_NUMBER_MIN`` property may contain a list of
+properties for this target whose minimum value may be read at generate
+time when evaluated in the ``INTERFACE`` variant of the property of all
+linked dependees. For example, if a
+property ``FOO`` appears in the list, then for each dependee, the
+``INTERFACE_FOO`` property content in all of its dependencies will be
+compared with each other and with the ``FOO`` property in the depender.
+When reading the ``FOO`` property at generate time, the minimum value
+will be returned. If the property is not set, then it is ignored.
+
+Note that for each dependee, the set of properties specified in this
+property must not intersect with the set specified in any of the other
+:ref:`Compatible Interface Properties`.
