validation of decimal with fractionDigits -- special case, additional zero digits
---------------------------------------------------------------------------------

         Key: XMLBEANS-208
         URL: http://issues.apache.org/jira/browse/XMLBEANS-208
     Project: XMLBeans
        Type: Bug
  Components: Validator  
    Versions: Version 2    
 Environment: Windows 2000 JDK 1.4 or JDK 1.5
    Reporter: Patrick Podenski
    Priority: Minor


I am encountering what I believe to be a bug in XML Beans 2 validation and would like \
some input on the expected validation behavior for the two test cases enclosed. The \
validation problem is related to a decimal with fractionDigits specified.  I have \
included all of the relevant information below.

For both XML instance documents, the XML Beans InstanceValidator produces a \
validation error. For the first case (1000.000001) I DO expect a validation error, \
however for the second (1000.000000) I DO NOT expect a validation error. This is \
because the W3C valiation rule states that additional trailing fractional zero digits \
are permitted.

If I validate using the oXygen 6.1 XML editor, (1000.000001) will produce a \
validation error as expected, and (1000.000000) validates successfully as expected.

-- Validation error for (1000.000001) using oXygen XML editor:

SystemID: C:\aaa_workspace\XMLBeans_Sandbox\test\simple_decimal_1.xml
Location: 1:31
Description: E cvc-fractionDigits-valid: Value '1000.000001' has 6 fraction digits, \
                but the number of fraction digits has been limited to 3.
URL: http://www.w3.org/TR/xmlschema-2/#cvc-fractionDigits-valid


-- From W3C [ http://www.w3.org/TR/xmlschema-2/#rf-fractionDigits ]:
"The term fractionDigits is chosen to reflect the fact that it restricts the value \
space to those values that can be represented lexically using at most fractionDigits \
to the right of the decimal point. Note that it does not restrict the lexical space \
directly; a non-canonical lexical representation that adds additional leading zero \
digits or trailing fractional zero digits is still permitted."

--  XML Beans InstanceValidator error message (same error for either test case):

test\simple_decimal_1.xml NOT valid.
C:\aaa_workspace\XMLBeans_Sandbox\test\simple_decimal_1.xml:2: error: \
cvc-fractionDigits-valid: Decimal fractional digits (6) of value '1,000' does not \
match fractionDigits facet (3) for dec15d3
