They do contain annotations to that effect. This is, however,
not a compatibility decomposition. No formal compatibility
mappings are provided for *any* such instances of cases where
two (or more) glyph part characters could be equated, if
placed in the correct sequence, to a single character that
stands for the entire concept. Cf., for example:
U+222B INTEGRAL = U+2320 TOP HALF INTEGRAL + U+2321 BOTTOM
HALF INTEGRAL
And all the possible equivalent sequences implied by the
various bracket and brace glyph piece characters now in
the standard.
U+3033..U+3035 are simply Asian character set compatibility characters
for cell-based graphic display, since these repeat signs generally
are double-character in height.
