TDS format properties for embedded simple type boolean types

The TDS format properties described here apply to:

Field Identification

Property Type Meaning
Tag String Specify the value 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.

Should the object be a complex element and the Data Element Separation property of its parent is Tagged Delimited, Tagged Fixed Length, or Tagged Encoded Length then 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 to be used by the parser to identify the data in the message to be assigned to the object. Used when the Data Element Separation method has been set to Use Data Pattern in the complex type. See Regular expression syntax for further details.
Repeating Element Delimiter String Specify the delimiter to be used between repeating elements.

Start of changeA default value might be provided if the element repeats. This will depend on the messaging standard and certain conditions that would also need to be met:End of change

Start of change
  • For HL7, the mnemonic <HL7_RS> is used, but only if the Data Element Separation is set to All Elements Delimited or Variable Length Elements Delimited.
  • For all other messaging standards, if the element repeats a fixed number of times, the delimiter of the parent group or complex type is used.
End of change

Start of changeIf the above rules are not met, a default will not be applied.End of change

This property does not apply to attributes..

Length Reference Enumerated type Specify the identifier of a sibling Integer object, the value of which dictates the length of the object in question. The sibling object must be defined before the current object within the message structure.
