The elements in the document should look like this:

<customer>John Smith</customer>

Or something like this:

<customer>John Smith</customer>

Note:If you use the string data type, the XML processor will not change the value in it.

The normalized string data type can also contain characters, but the XML processor will remove line breaks, carriage returns, and tabs.

<xs:element name="customer" type="xs:normalizedString"/>

The elements in the document should look like this:

Or something like this:

<customer>John Smith</customer>
