This function will compare the value of the two given instance ids. When no options are specified, this function will behave exactly as the Express operation "inst1 = inst2" (value compare instances). By default, only explicit attributes will be compared. The format of this string is 'instId1 = 12345; instId2 = 987654; attrId = 76859;'

Arguments

Type	Name	Comment
GENERIC	instId1	Instance id 1
GENERIC	instId2	Instance id 1
INTEGER	options	options for the function
GENERIC	includeORexcludeRoles	optional argument, i.e., may be specified as "?" (indeterminate)
GENERIC	includeORexcludeTypes	optional argument, i.e., may be specified as "?" (indeterminate)
STRING	errorInformation	optional argument, i.e., may be specified as "?" (indeterminate) Will receive a STRING defining the actual two instances and the actual role compared when an inequality is found.

Return Value

Type	Name	Comment
LOGICAL	isValueEquals	output

Options

Option	Comment
XPXCOMPARE_INDETERMINATE_AS_VALUE	This options specifies that the values INDETERMINATE and UNKNOWN should compared by their "numeric values" as follows: INDETERMINATE = INDETERMINATE -> TRUE INDETERMINATE = NOT(INDETERMINATE) -> FALSE UNKNOWN = UNKNOWN -> TRUE UNKNOWN = NOT(UNKNOWN) -> FALSE;
XPXINCLUDE_DERIVE_ATTRIBUTES	The value of Derive attributes will be compared
XPXINCLUDE_INVERSE_ATTRIBUTES	The value of Inverse attributes will be compared
XPXINCLUDE_SPECIFIED_ROLES	Only the roles (attributes) specified in the "includeORexcludeRoles" aggregate will be compared. A role can be specified as an entityId (entity_definition object) or as a fully qualified attribute, i.e., 'EntityName.AttributeName',
XPXEXCLUDE_SPECIFIED_ROLES	All roles (attributes) except those specified in the "includeORexcludeRoles" aggregate will be compared. A role can be specified as an entityId (entity_definition object) or as a fully qualified attribute,i.e., 'EntityName.AttributeName'.
XPXINCLUDE_ROLES_IN_SUBTYPES	This option has only effect when one of the options XPXINCLUDE_SPECIFIED_ROLES or XPXEXCLUDE_SPECIFIED_ROLES are specified and the actual roles in the "includeORexcludeRoles" aggregate are specified as a STRING ('EntityName.AttributeName'), The effect of this option is that all specified roles in the "includeORexcludeRoles" aggregate will include the role with the same name in all subtype instances of the actual specified instance type ('EntityName').
XPXINCLUDE_SPECIFIED_TYPES	Only instances of the types specified in the 'includeORexcludeTypes' aggregate will be compared, i.e., the "comparison" of all other instance types will result in TRUE. The elements in the 'includeORexcludeTypes' aggregate can be specified as an entityId or as an EntityName; NOTE: The instance types specified in the 'includeORexcludeTypes' aggregate will not have any effect for the comparison of the actual two instances given as arguments to the xpfValueCompareInstances() function.
XPXEXCLUDE_SPECIFIED_TYPES	All instances of any types except those instance types specified in the 'includeORexcludeTypes' aggregate will be compared, i.e., the "comparison" of all other instance types will result in TRUE. The elements in the 'includeORexcludeTypes' aggregate can be specified as an entityId or as an EntityName; NOTE: The instance types specified in the 'includeORexcludeTypes' aggregate will not have any effect for the comparison of the actual two instances given as arguments to the xpfValueCompareInstances() function
XPXINCLUDE_SYBTYPES_OF_TYPES	This option has only effect when one of the options XPXINCLUDE_SPECIFIED_TYPES or XPXEXCLUDE_SPECIFIED_TYPES are specified. The effect of this option is that all instance types specified in the 'includeORexcludeTypes' aggregate will include all subtypes of the specified instance types.
