There seems to be a contradiction here. “Decomposable character” is
defined in clause 3.7 as follows:

“A character that is equivalent to a sequence of one or more other
characters, according to the decomposition mappings found in the Unicode
Character Database, and those described in Section 3.12, Conjoining Jamo

I suppose the intended meaning in clause 16.4, given its context, is to
say that the base character is neither a combining character nor a
character with a decomposition that contains a combining character.
