Hi,

the XSV team wanted to be informed of "violation of constraints on
exponents" warnings.

For the example further down, XSV reports:

bug310264.xml:9,1: content of c is not allowed to end here (4),
expecting [u'++(b)', u'{http://myns}:a']:

Plus:

<schemaWarning ...>violation of constraints on exponents</schemaWarning>

(Note that this is a reduced version from a bug report
submitted by Tom Moog for Libxml2:
http://bugzilla.gnome.org/show_bug.cgi?id=310264)

bug310264.xsd:
<xs:schema xmlns:tns="http://myns"
	targetNamespace="http://myns"
	xmlns:xs="http://www.w3.org/2001/XMLSchema">

	<xs:element name="a" />
	<xs:complexType name="c" >
		<xs:sequence minOccurs="1" maxOccurs="2">
        		<xs:sequence minOccurs="2" maxOccurs="3">
            			<xs:element ref="tns:a" />
			</xs:sequence>
		</xs:sequence>
	</xs:complexType>
	<xs:element name="c" type="tns:c" />
</xs:schema>

bug310264.xml:
<c xmlns="http://myns"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://myns bug310264.xsd">
   <a/> <!-- 1 -->
   <a/> <!-- 2 -->
   <a/> <!-- 3 -->
   <a/> <!-- 4 -->      
</c>

MSXML 4.0 reports:
bug310264.xml:9,3: Element content is incomplete according to the
DTD/Schema.

Xerces-J 2.5.1 (I have currently no recent version at hand) does
not report an error.

Regards,

Kasimier
