PM10599: SHOULD COLLAPSE WHITESPACES IN LIST TYPE WITH STAX FLAVOR

APAR status

• Closed as program error.

Error description

• Schema Part 2 section 4.3.6 has:
  whiteSpace is applicable to all atomic and list datatypes.
  For all atomic datatypes other than string (and types
  derived by restriction from it) the value of whiteSpace is
  collapse and cannot be changed by a schema author;....
  For all datatypes derived by list the value of whiteSpace
  is collapse and cannot be changed by a schema author.
  
  STAX flavor is using XLXP parser which doesn't support
  validation, so it uses ValidatorHandler to do validation.
  However the chars fired by character events don't have
  whitespace collapsed.

  Running xpath20 test schematreatas20_657 in stax flavors,
  should return text nodes with a space as separator, but got
  result with whitespaces including line return, tab, spaces in
  between the text nodes.
  

Problem conclusion

• Schema Part 2 section 4.3.6 has:
  whiteSpace is applicable to all ?atomic? and ?list? datatypes.
  For all ?atomic? datatypes other than string (and types
  ?derived? by ?restriction? from it) the value of whiteSpace is
  collapse and cannot be changed by a schema author;....
  For all datatypes ?derived? by ?list? the value of whiteSpace
  is collapse and cannot be changed by a schema author.
  
  STAX flavor is using XLXP parser which doesn't support
  validation, so it uses ValidatorHandler to do validation which
  does not collapse whitespaces in characters events.
  
  Wrote a new ContentHandler implementation to collapse
  whitespace in Characters event to handle StAX.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 1.0.0.5. Please refer to the Recommended Updates
