Syntax table 12-3 says that the thing following the ':' of a case item is a
generate_item_or_null. This is:
generate_item_or_null ::=
generate_item
| ;
generate_item ::=
generate_conditional_statement
| generate_case_statement
| generate_loop_statement
| generate_block
| module_or_generate_item

A generate item consists of exactly one statement or declaration. Note that
a generate_block (begin/end) counts as one item. So if you want, say, two
instantiations after the ':' of a case statement, you have to use a generate
block anyway.
