XML wire format: relationship to the logical model

The XML wire format generally respects all of the setting in the logical model, but shares certain restrictions in common with the other physical formats. These restrictions are documented in MRM model restrictions.

Default values

The XML wire format ignores default and fixed values on elements and attributes. If validation is enabled in WebSphere Business Integration Message Broker, this can lead to unexpected validation errors for missing elements, even though they have default or fixed values.

Simple types – unions and lists

The XML properties of an element or attribute of a simple type that is a union or list vary depending on the members of the union or the itemType of the list. If the union or list includes a dateTime type (or other date/time related type) the Date Format field will be displayed. If the union includes a binary type, the Encoding field will be displayed.
