Definition

1.	No <Property> instance, other than a <Table Property Description>, shall have an SE_Index_Code meaning value.
2.	Consider a <Data Table> instance DT, with a component <Table Property Description> instance X, where X has a meaning value of SE_INDEX_CODE_DATA_TABLE_LIBRARY. For each corresponding cell value N in the <Data Table> instance DT, if N is not a sentinel value for missing or excluded, N is an index into the ordered set of <Data Table> components of a <Data Table Library> where
	2.1 The transmittal in which the <Data Table> DT resides shall have a <Data Table Library> L, 2.2 The <Data Table Library> L shall have at least N ordered <Data Table> components, 2.3 The Nth <Data Table> component of the <Data Table Library> L shall have a <Classification Data>, the tag of which matches the component_data_table_ecc of the <Table Property Description> instance X.   2.3.1 If the <Classification Data> of the referenced Nth <Data Table> has no component <Property Values>, the <Table Property Description> instance X shall have none. 2.3.2 If the <Classification Data> of the referenced Nth <Data Table> has j component <Property Values>, the <Table Property Description> instance X shall have exactly j matching <Property Values>.
3.	Consider a <Data Table> instance DT, with a component <Table Property Description> instance X, where X has a meaning value of SE_INDEX_CODE_DATA_TABLE_COMPONENT. For each corresponding cell value N in the <Data Table> instance DT, if N is not a sentinel value for missing or excluded, N is an index into the ordered set of <Data Table> components of DT, where
	3.1 The <Data Table> DT shall have at least N ordered <Data Table> components, 3.2 The Nth <Data Table> component of DT shall have a <Classification Data>, the tag of which matches the component_data_table_ecc of the <Table Property Description> instance X.   3.2.1 If the <Classification Data> of the referenced Nth <Data Table> has no component <Property Values>, the <Table Property Description> instance X shall have none. 3.2.2 If the <Classification Data> of the referenced Nth <Data Table> has j component <Property Values>, the <Table Property Description> instance X shall have exactly j matching <Property Values>.
4.	Consider a <Data Table> instance DT, with a component <Table Property Description> instance X, where X has a meaning value of SE_INDEX_CODE_PROP_TABLE_REF_COMPONENT. For each corresponding cell value N in the <Data Table> instance DT, if N is not a sentinel value for missing or excluded, N is an index into the ordered set of <Property Table Reference> components of DT, where
	4.1 The <Data Table> DT shall have at least N ordered <Property Table Reference> components, 4.2 The Nth <Property Table Reference> component of DT shall refer to a <Property Table> such that its <Classification Data> tag matches the component_data_table_ecc of the <Table Property Description> instance X.   4.2.1 If the <Classification Data> of the referenced <Property Table> has no component <Property Values>, the <Table Property Description> instance X shall have none. 4.2.2 If the <Classification Data> of the referenced <Property Table> has j component <Property Values>, the <Table Property Description> instance X shall have exactly j matching <Property Values>.

5.

A <Table Property Description> instance which is not covered by 2, 3, or 4 above shall have no <Property Value> components.

6.

Consider a <Data Table> instance DT, with a component <Table Property Description> instance X, where X has a meaning value of SE_INDEX_CODE_IMAGE_MAPPING_FUNCTION. For each corresponding cell value N in the <Data Table> instance DT, if N is not a sentinel value for missing or excluded, N is an index into the ordered set of <Image Mapping Function> components of DT, where the <Data Table> DT shall have at least N ordered <Image Mapping Function> components.

Rationale

1. The SE_Index_Code enumerants that exist to allow cells within <Data Table> instances to reference <Data Table Library> component <Data Table>, component <Data Table>, component <Property Table Reference>, and component <Image Mapping Function> instances are meaningless for all other <Property> contexts.

2. The only function of <Property Value> components for the <Table Property Description> class to provide elaboration for the meaning field as needed, since in general, referenced <Data Table> instances are distinguished only by their classification (which may be elaborated).

Example

1. Consider a <Property Table> instance containing two <Table Property Description> instances defining indices to sub-tables (that is, two elements in each cell are such indices, and the <Property Table> itself has two component <Property Table> instances).

   The first index references sub-tables classified by ECC_WATER_BODY_ACOUSTIC_PROPERTY_SET with <Property Value> elaboration EAC_FREQUENCY = 100 Hz.

   The second index references sub-tables classified by ECC_WATER_BODY_ACOUSTIC_PROPERTY_SET with <Property Value> elaboration EAC_FREQUENCY = 2000 Hz.
