[Debian-med-packaging] Bug#859650: Schemas validity error : Element 'value': '6.1035156E-5' is not a valid value of the atomic type 'DecimalString

Looks like dsr2xml.xsd is a bit too restrictive on it's representation
of VR:DS as used in a DICOM SR instance.

Eg:

$ xmllint --noout --schema /usr/share/dcmtk/dsr2xml.xsd test.xml
test.xml:253: element value: Schemas validity error : Element
'{http://dicom.offis.de/dcmsr}value': '6.1035156E-5' is not a valid
value of the atomic type '{http://dicom.offis.de/dcmsr}DecimalString'.

with:

            <num>
              <relationship>CONTAINS</relationship>
              <concept>
                <value>NUM00060</value>
                <scheme>
                  <designator>FOO</designator>
                </scheme>
                <meaning>Vector (X)</meaning>
              </concept>
              <value>6.1035156E-5</value>
              <unit>
                <value>XYZ</value>
                <scheme>
                  <designator>UCUM</designator>
                </scheme>
                <meaning>Arbitrary Unit</meaning>
              </unit>
            </num>


The file dsr2xml.xsd rely on the use of xsd:decimal which restricts:

The following values are invalid: 1 234.456 (spaces are forbidden),
1234.456E+2 (scientific notation—E+2—is forbidden), + 1234.456 (spaces
are forbidden), or +1,234.456 (delimiters between thousands are
forbidden).
