| 6.1 <collection type> is as following: |
| <blockquote><pre> |
| <collection type> ::= |

| <array type> ::= |
| <data type> ARRAY |
| [ <left bracket or trigraph> |

| <maximum cardinality> ::= |
| <unsigned integer> |
| |
| <multiset type> ::= |

| </pre></blockquote> |
| |
| <p>This class is intended to describe SQL collection type. It can describe |

| "int array array" or "int array multiset". For nested collection type, the element type |
