The following instance document will not work:
<?xml version = "1.0" ?>
<employee xmlns = "http://www.wbex.ru/employees"
employeeID = "2442"
clubCardMember = "true">
<FirstName>first</FirstName>
<MiddleInitial>middle</MiddleInitial>
<LastName>last</LastName>
</employee>
The schema is expecting that we qualify the globally declared attribute name.
It wants to see the following:
<?xml version = "1.0" ?>
<employee xmlns = "http://www.wbex.ru/employees"
xmlns:cust = "http://www.wbex.ru/employees"
clubCardMember = "true"
cust:employeeID = "2442">

<MiddleInitial>middle</MiddleInitial>
<LastName>last</LastName>

==If the schema had a value of unqualified for elementFormDefault it would look like so RussianDoll_eu_au.xml==

==Requiring All Elements and Attributes Be Qualified==



<source lang="xml">

<?xml version = "1.0" ?>
<schema xmlns = "http://www.w3.org/2001/XMLSchema"
targetNamespace = "http://www.wbex.ru/employees"
xmlns:cust = "http://www.wbex.ru/employees"
elementFormDefault = "qualified"
attributeFormDefault = "qualified">

<element name = "employee" type = "cust:employeeType" />

<complexType name = "employeeType">
<sequence>
<element name = "FirstName" type = "string" />
<element name = "MiddleInitial" type = "string" />
<element ref = "cust:LastName" />
</sequence>
<attribute name = "clubCardMember" type = "boolean" />
<attribute ref = "cust:employeeID" />
</complexType>

<element name = "LastName" type = "string" />
<attribute name = "employeeID" type = "integer" />

</schema>
We could qualify each element and attribute individually like so:
<?xml version = "1.0" ?>
<cust:employee xmlns:cust = "http://www.wbex.ru/employees"
cust:clubCardMember = "true"
cust:employeeID = "24427">
<cust:FirstName>Ray</cust:FirstName>
<cust:MiddleInitial>G</cust:MiddleInitial>
<cust:LastName>Bayliss</cust:LastName>
</cust:employee>
But the following would NOT be valid:
<?xml version = "1.0" ?>
<employee xmlns = "http://www.wbex.ru/employees"
clubCardMember = "true"
employeeID = "24427">
<FirstName>first</FirstName>
<MiddleInitial>middle</MiddleInitial>
<LastName>last</LastName>
</employee>
</source>

==using local element declarations for the children of the employee element==



<source lang="xml">

<?xml version = "1.0"?>
<schema xmlns = "http://www.w3.org/2001/XMLSchema"
targetNamespace = "http://www.wbex.ru/employees"
xmlns:cust = "http://www.wbex.ru/employees">

<element name = "employee" type = "cust:employeeType" />

<complexType name = "employeeType">
<sequence>
<element name = "FirstName" type = "string" />
<element name = "MiddleInitial" type = "string" />
<element name = "LastName" type = "string" />
</sequence>
</complexType>

</schema>
The following will not work in an instance document,
because we are only expected to qualify globally declared elements and attributes.
<?xml version = "1.0" ?>
<employee xmlns = "http://www.wbex.ru/employees">
<FirstName>Ray</FirstName>
<MiddleInitial>G</MiddleInitial>
<LastName>Bayliss</LastName>
</employee>
The proper way of showing this in a document is:
<?xml version = "1.0" ?>
<cust:employee xmlns:cust = "http://www.wbex.ru/employees">
<FirstName>first</FirstName>
<MiddleInitial>middle</MiddleInitial>
<LastName>last</LastName>
</cust:employee>
</source>
