If all that is desired is to call attention to the fact that the copy text has been corrected, corr may be used alone:
It is also possible, using the choice and sic elements, to provide an uncorrected reading:
<content> <macroRef key="macro.paraContent"/></content>
element corr { tei_att.global.attributes, tei_att.editLike.attributes, tei_att.typed.attributes, tei_macro.paraContent }
