19.20 specifies @Indexes
19.21 specifies @Indices
They appear to be identical in intent, serving as containers when
more than @Index annotation is required. JPOX treats them as the
same annotation, differing only in name.
It seems redundant and potentially confusing to include both of
these; I suggest we choose one.
While the dictionary (New Oxford American) treats both 'indexes' and
'indices' as valid plural forms of 'index', it notes that 'indices'
is favored "especially in technical contexts". Perhaps we can let
that be the deciding vote?
