MSXML version 4, SAX parser using C++
The parser is removing line feeds from a text field that is being returned 
to the content handler. The line feeds are necessary for other processing. I 
have tried different variations of the preserve whitespace option in the xsd 
validation file but it still removes them. Here is the relevant section of 
the xsd:

<xs:simpleType name="commentType">
	<xs:restriction base="xs:string">
		<xs:whiteSpace value="preserve"/>
	</xs:restriction>
</xs:simpleType>
<xs:element name="comment" type="commentType" />

<xs:element name="comment_list">
    <xs:complexType>
      <xs:sequence>
        <xs:element minOccurs="1" maxOccurs="unbounded" ref="comment" />
      </xs:sequence>
    </xs:complexType>
</xs:element>

For example, the comment comes in the xml as:

<comment>[x]aaa
[y]bbb
[z]ccc<comment>

and the SAXContentHandlerImpl derived character function in the content 
handler provides [x]aaa[y]bbb[z]ccc

It would be also be OK to preserve whitespace globally if there is a 
property or feature that can be set within the SAXXMLReader40 or 
XMLSchemaCache40 objects.

Any suggestions?  We had assumed the Preserving Whitespace would have left 
the linefeeds intact, but so far, no luck.
