A naked newline (or any other line ending sequence normalized to a naked newline) in an attribute value is converted to a space: http://www.w3.org/TR/2008/REC-xml-20081126/#AVNormalize Tab and carriage return are the only other control characters allowed in XML 1.0: http://www.w3.org/TR/2008/REC-xml-20081126/#NT-Char If you want all other control characters except NUL, use XML 1.1: http://www.w3.org/TR/2008/REC-xml-20081126/#NT-Char For a client of mine who needed to feed a legacy print application I had to write one of my stylesheet fragments in XML 1.1 in order to get the control characters they needed: http://sportsmlt.svn.sourceforge.net/viewvc/sportsmlt/2.0/support/sportsmlt2-character.xsl?revision=13&view=markup I hope this helps. . . . . . . . . .
