For example, Let's say you create a form and a workflow that uses that form as a step from an Address Book schema. The form created from this schema contains Title, Last Name, Address2, Zip code, Home Phone and Gift Idea fields among others. You make these updates to the schema then update it as described above.
- Changed the minOccurs value for the Title field to 1 making it required.
- Deleted the Last Name field from the schema
- Moved the Home Phone field into the Address section and removed the Zip Code field from the Address section
- Added a Number of Members in Family field to the schema.
When you edit the form/workflow step, after updating the schema, warnings and instructions will show for any controls that have become unbound etc. Notice the Number of Members in Family field has been added to the Data Source and now can be added to the form/workflow.
Although we do not recommend leaving unbounded controls in your form, you are not explicitly prevented from doing so. If you save your form with unbounded controls, data submitted in these controls will be included in the default XML Submission document for the form itself as opposed to being captured in the XML document for the schema.
