The Northwind Traders BizTalk Schema

In Chapter 7, we created a schema based on the W3C standard for the Northwind Traders database. This schema rewritten as a BizTalk schema is shown here.

  <Schema name="NorthwindSchema"
     xmlns="urn:schemas-microsoft-com:xml-data"

As you can see, a few changes have been made between the W3C version and the BizTalk version of this schema. The annotation elements have been replaced by description elements. There is no equivalent to the W3C datatype element, nor can you set a continuous range of values (such as 1 through 100). Also, the data type content has been replaced with the content attribute.
