  Subject: XML Schema to XML producing invalid document

Hello,
I'm using Stylus Studio to generate sample XML files based on an XSD I've created, and the files it produces then fail to validate against the same XSD. Thus far, I can't determine if it's my XSD which is misusing some portion of the Schema specification or if it's due to a Stylus bug.
The section of the XSD which proves problematic is structured like this:
<xs:complexType name="Drawing">
<xs:sequence>
<xs:element name="drawingType" type="xs:string"/>
<xs:choice maxOccurs="1">
<xs:sequence>
<xs:element name="drawingFirstDrawingDate" type="xs:date"/>
<xs:element name="drawingFrequency" type="xs:string"/>
<xs:element name="drawingCount" type="xs:int"/>
<xs:element name="drawingEndDate" type="xs:date"/>
</xs:sequence>
<xs:element name="drawingSchedule" type="AmountScheduleElement" maxOccurs="unbounded" />
</xs:choice>
<xs:element name="drawingInterest" type="Interest" minOccurs="0" maxOccurs="unbounded"/>
<xs:element name="drawingTenor" type="Tenor"/>
</xs:sequence>
</xs:complexType>
For choices and substitution groups, I have configured Stylus to "Generate all; all except first instance are commented"
In the resulting XML file, I get:
<facilityDrawingParameters>
<drawingType>string</drawingType><!--
<drawingFirstDrawingDate>1999-01-21</drawingFirstDrawingDate>
<drawingFrequency>string</drawingFrequency>
<drawingCount>-2147483648</drawingCount>
<drawingEndDate>1999-01-21</drawingEndDate>--><!--
<!--Element drawingSchedule, maxOccurs=unbounded-->
<drawingSchedule date="1999-01-21">
<value>
<amount>
<nominal>1.23</nominal>
<currency>string</currency>
</amount><!--
<rate>0</rate>-->
</value>
</drawingSchedule>
...-->
<!--Element drawingInterest is optional, maxOccurs=unbounded-->
<drawingInterest>
...
</drawingInterest>
<drawingInterest>
...
</drawingInterest>
<drawingInterest>
...
</drawingInterest>
<drawingTenor>
...
</drawingTenor>
</facilityDrawingParameters>
(ellipses ... used to remove content not pertinent to this question)
Stylus complains appropriately, upon validation of this XML, that:
Element 'drawingInterest' is not valid for content model: '((drawingType,(((drawingFirstDrawingDate,drawingFrequency,drawingCount),drawingEndDate)|drawingSchedule),drawingInterest),drawingTenor)'
Shouldn't Stylus be omitting the comment marks which enclose the first sequence of four elements generated after the drawingType element, based on my settings? If I manually remove the comment marks, the document validates properly.
Thanks in advance for any assistance you can provide.
