+Properties whose maximum value from the link interface will be used.
+
+The COMPATIBLE_INTERFACE_NUMBER_MAX property may contain a list of
+properties for this target whose maximum value may be read at generate time
+when evaluated in the INTERFACE 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 maximum value will be returned.

+:prop_tgt:`COMPATIBLE_INTERFACE_STRING` or
