vtkXMLWriter::ReserveAttributeSpace does not reserve enough
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
The original version of vtkXMLWriter::ReserveAttributeSpace was intended to write the empty space for an XML attribute value that will be a 32-bit integer. Since then uses of the method have been added for 64-bit integers and double-precision floating-point values. The method no longer reserves enough space. It should be re-written to have an interface that allows specification of the longest possible value.
