According to the spec page:239,240, Select clause can have single valued expression or Object(identifier).
select_clause ::=SELECT [DISTINCT ] {single_valued_path_expression |
OBJECT (identification_variable)}
single_valued_path_expression ::=
{single_valued_navigation | identification_variable}.cmp_field |
single_valued_navigation
single_valued_navigation ::=
identification_variable.[single_valued_cmr_field.]* single_valued_cmr_field
I think "You can't use dot notation to return a Collectiontype CMR field"
