#133 problem with pyxbgen when the xsd has a <xsd:choice> entry

PyXB 1.2.0
Binding model
PyXB 1.1.3
Bill Riegel

I've modified the po.xsd and po.xml to include
a choice under the item entry


<xsd:element name="USPrice" type="xsd:decimal" minOccurs="0"/>

<xsd:element ref="po:comment" minOccurs="0"/>


if and when you have an item with only a USPrice and another item
with only a comment, you get the following error

pydev debugger: starting

Poc.xsd is the modified xsd
Poc.xml is the example xml file

The error is seen when i run pocsample.py
