No time for a long explanation and references, but the quick answer
<sic corr="&longs;">f</sic>h<orig reg="ie">y</orig>ld
This allows extraction of all 4 combinations:
fhyld SIC and ORIG diplomatic
&longs;hyld corr= and ORIG corrected
fhield SIC and reg= regularized
shield corr= and reg= corrected & regularized
Time to go home.
