Elements with the same name (but different location) make Unmarshaller fail

Here is an example mapping document fragment:

<class name="AnyClass">
<map-to xml="test">
<field name="urlOne" type="java.lang.String">
<bind-xml name="url" />
</field>

<field name="urlTwo" type="java.lang.String">
<bind-xml name="url" location="two"/>
</field>
</class>

and a sample input file:

<test>
<url>first URL</url>
<two>
<url>second URL</url>
</two>
</test>

This causes:

unable to add 'url' to <test> due to the following exception:
>>>--- Begin Exception ---<<<

Note that I can play with different XML/mapping file combinations:

<test>
<one>
<url>...</url>
</one>
<two>
<url>...</url>
</two>
</test>

This fails too.

Same problem exists in 0.9.5.4.
