I have created two basic XML vocabularies: Address and Person. I have created an Address XSD schema (which doesn't have any dependencies on other schemas) - and this correctly validates an input address.xml doc.
I have created a Person XSD schema which imports the Address XSD. My Person.xml (which is mixed-vocab file) fails it's validation with the following error:
XML validation started.
Checking file:[...]/validator/src/main/resources/person.xml...
Referenced entity at "file:[...]/validator/src/main/resources/person.xsd".
Referenced entity at "file:[...]validator/src/main/resources/address.xsd".
cvc-complex-type.2.4.a: Invalid content was found starting with element 'a:address'. One of '{"urn:person.com.test":address}' is expected. [11]
XML validation finished.
It appears from the error that the 'Address' type is now mapped (by the import?) to the 'Person' type.
I need to keep my input document in such a format as to ensure two namespaced vocabs are identifiable in the input document (I can't refactor my input document in such a way as to remove the two namespaces - I can't just shove everything into the 'Person' namespace for instance).
What am I doing wrong here ?
Here are my files:
Address.xsd:

'Address.xml' - An example of instance document which validates correctly against the schema above:
<?xml version="1.0" encoding="UTF-8"?>
<a:address
xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
xmlns:a='urn:address.com.test'
xsi:schemaLocation='urn:address.com.test address.xsd'>
<a:Street_name>10 Downing Street </a:Street_name>
<a:Town_City>London</a:Town_City>
<a:Country>UK</a:Country>
<a:Postcode>SW1A 2AA</a:Postcode>
</a:address>
The Person.xsd: with the import to Address.xsd:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema version="1.0" xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="urn:person.com.test"
xmlns="urn:person.com.test"
xmlns:p="urn:person.com.test"
xmlns:a="urn:address.com.test"
elementFormDefault="qualified">
<xs:import namespace="urn:address.com.test" schemaLocation="address.xsd"/>
<xs:element name="person" type="Person" />
<xs:complexType name="Person">
<xs:sequence>
<xs:element name="first_name" type="xs:string" />
<xs:element name="last_name" type="xs:string"/>
<xs:element name="address" type="a:Address"/>
</xs:sequence>
</xs:complexType>
</xs:schema>
And the 'Person.xml' - the mixed-vocab document which fails validation:
<?xml version="1.0"?>
<p:person
xmlns:p="urn:person.com.test"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="urn:person.com.test person.xsd">
<p:first_name>Joe</p:first_name>
<p:last_name>Bloggs</p:last_name>
<a:address xmlns:a="urn:address.com.test">
<a:Street_name>10 Downing Street</a:Street_name>
<a:Town_City>London</a:Town_City>
<a:Country>UK</a:Country>
<a:Postcode>SW1A 2AA</a:Postcode>
</a:address>
</p:person>
I'm using Netbeans 8 to run the validation.
EDIT:
From the accepted answer ; the change I opted for was to change the following in Person.xsd:
From:
<xs:element name="address" type="a:Address"/>
To:
<xs:element ref="a:address"/>
Note that that former refered to the complex type definition "Address" (uppercase 'A' in my example); and the latter refers to the global element definition 'address' (lowercase 'a').
