RE: [sdo] NEW ISSUE: Mapping of signed and unsigned integer values

Hi Bryan,

 

As far as the mapping of XSD byte to SDO Byte, SDO 
2.1.1 will fix this and make SDO Byte a signed value.

Subject: [sdo] NEW ISSUE: 
  Mapping of signed and unsigned integer values

  

Target: Core specification WD-01 
  Section 6.1, 7.4, and 8.1 
  
            Java specification WD-02 Section 7.1, and 
  8.3? 
        
      C++ specification WD-02 Section 8.1

Description: 
  

Currently the 
  SDO type Byte is defined as an 8-bit unsigned integer, while Short, 
  Int, and Long are 16, 32 and 64 bit signed integers 
  respectively 
Why are the not any SDO types for unsigned 
  16, 32, and 64 bit integers (which are valid XSD types)?  Or for that 
  matter an 8-bit signed integer (which is what XSD:byte is)? 

A 
  related concern the mapping of XSD:byte to SDO Byte appears to be an error 
  since -123 would be a valid value in the XML document but not in the SDO 
  instance.
