XML schema validation fails
 

Hi,

currently I have a little problem upon saving some excel worksheets as
xml data. Normally cell's without a value are not exported into xml,
because in my schema they are marked as optional (see schema below).
But sometimes values are copy-pasted into the worksheet and I'll get
the following error message while saving from the schema validation:
"Error parsing '' as decimal datatype. The attribute 'Exposure' with
value '' failed to parse."

I can't find any differences to other "empty" cells - same format,
formula and value are blank.

Any ideas?

Kind regards,
Michael


Here is the schema I use:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified"
<xs:element name="test"
<xs:complexType
<xs:sequence
<xs:element ref="myType" maxOccurs="unbounded" /
</xs:sequence
</xs:complexType
</xs:element
<xs:element name="myType"
<xs:complexType
<xs:attribute name="Exposure" type="Amount" use="optional" /
</xs:complexType
</xs:element
<xs:simpleType name="Amount"
<xs:restriction base="xs:decimal"
<xs:minInclusive value="0" /
<xs:fractionDigits value="12" /
</xs:restriction
</xs:simpleType
</xs:schema
