xsi:SchemaLocation="http://www.microsoft.com family.xsd
http://www.codew3c.com attribute.xsd">
<person gender="female">
<firstname>Jane</firstname>
<lastname>Smith</lastname>
</person>
<person gender="male">
<firstname>David</firstname>
<lastname>Smith</lastname>
</person>
</persons>

This XML file is valid because the schema "family.xsd" allows us to add attributes to the "person" element.

Both <any> and <anyAttribute> can be used to create extensible documents! They make documents capable of including additional elements that are not declared in the main XML schema.
