Sets whether the element can be repeated an unknown number of times at runtime before the import or export moves on to the next element.
Yes if the element can be unbound; otherwise, No. The default value is No.
If you design an XMLport that is used to import or export data in different formats where the number of columns can vary, you can use this property to handle the number of columns.
If this property is set to Yes, then your code for handling exports must specify when to break to the next element by using the BREAKUNBOUND function.
During an import, the XMLport will automatically move on to the next record when the code reaches a record separator.
For example, your XMLport can export data in two different file formats. One format contains 5 columns, and the other contains 10 columns. Instead of duplicating the maximum number of columns and writing code that skips any redundant columns, you can set up a single column, make it unbound, and then specify in code when to break to the next element.
