space) should be preceded by a hash mark ("#"):

    <choice><corr>...(Former text inside of corr goes
   here)...</corr><sic>...(value of the "sic" attribute now goes here
   instead)...</sic></choice>

15) Every <sic> with a "corr" attribute should be:
   <choice><corr>...(Value of the corr attribute goes
   here)...</corr><sic>...(text inside of <sic> now goes here
   instead)...</sic></choice>

16) Every <abbr> with a "expan" attribute or <expan> with an "abbr"

   changed to the "who" attribute of the enclosing <change>

   directly inside <change>
