Final Information Model
1- Revise the Schema from Feedback
Take your schema (minus your root tag) and add it to infoneed.xsd under the <myElements>
element. Notice that my schema has an id and title for your items already, so remove any that
you put in your schema. Also, add any management elements you may have invented, to create
a final draft. Provide screen shot(s) of your schema below.
2- Create a Sample Instance
Create a sample XML instance file that tests all of the elements and attributes of your schema.
Paste the content of the instance in the space below:
3- Revise the Schema from the Instance
During and after creating the instance, it is very likely that you will want to modify your schema. If
you did, then take a new screen shot and replace the one above. Summarize the changes you
needed to make in the space below:
