== Why is this an issue?

Having multiple prefixes for the same namespace is highly likely to confuse users and maintainers of the schema.


=== Noncompliant code example

[source,xml]
----
<xs:schema targetNamespace="http://www.codeSamples.com/fruit"
           elementFormDefault="qualified" version="1"
           xmlns:xs="http://www.w3.org/2001/XMLSchema"
           xmlns:animal="http://www.codeSamples.com/animal"
           xmlns:beast="http://www.codeSamples.com/animal">    <!-- Noncompliant -->
  ...
</xs:schema>
