Both the 2.1 and 2.0 specs' definition for the 'table' attribute
"If the join is for a unidirectional OneToMany mapping using a foreign
key mapping strategy, the name of the table of the target entity."
It seems like the table would be implicitly known (and would not need
to be explicitly specified) in a case where the column does reside in
the default target entity table. Does the existence of the 'table'
attribute not suggest something other than the default case? Curious
about what other meaning the table could have here if not to specify a
table other than the default target entity table.
