Message Sets: TDS properties for embedded simple type binary types

Field identification and physical representation.

The TDS properties described here apply to:

Field identification

Property Type Meaning
Tag String Specify the value that is used to identify the object in a message bit stream.

If the object is simple and the Data Element Separation property of the complex type or types in which the object is a child is Tagged Delimited, Tagged Fixed Length, or Tagged Encoded Length, this property must contain a non-empty value.

If the object is a complex element, and the Data Element Separation property of its parent is Tagged Delimited, Tagged Fixed Length, or Tagged Encoded Length, the property can contain an empty value.

The value for this property must be unique for every element in the message set; that is, no two elements in the message set can contain the same value for this property.

Data Pattern String Specify the regular expression that the parser uses to identify the data in the message to assign to the object. This property is used when the Data Element Separation method is set to Use Data Pattern in the complex type. For more details, see Message Sets: Regular expression syntax.
Repeating Element Delimiter String Specify the delimiter to use between repeating elements.

This delimiter is used only when the element repeats and the Data Element Separation property of the parent group or complex type is set to All Elements Delimited or Variable Length Elements Delimited.

A default value is provided if the previous conditions are true; if the messaging standard is HL7, the mnemonic <HL7_RS> is used; if the messaging standard is not HL7, and the maximum number of repeats is fixed, the delimiter of the parent group or complex type is used.

If none of the previous conditions are true, a default is not applied.

Physical representation

Property Type Meaning
Length Integer Specify the expected length of the object in length units.

A non-zero length must be specified if no Length Reference is specified.

The default is dependent on the setting of the message set property Derive default length from logical type. If Derive default length from logical type is selected, the default value is derived from any length or maxLength value constraint (schema facet) on the object's simple type.

Length Reference Enumerated type This property is applicable only if Physical Type is Text, Binary, or TLOG Specific. If set, this property takes precedence over any value in the Length Units property.

Specify the identifier of a sibling integer object, the value of which determines the length of the object in question. The sibling object must be defined before the current object within the message structure.
