Presumably for certain XML processing, IBM has made taking care of the messy details relatively (FSVO relatively) simple. Note that though there is XML source code in the COBOL source the actual executed XML code and routines probably are separately dynamically called routines in some other source language. I also assume that COBOL programs that use the SORT verb are implicitly taking advantage of any zXXP capability of the invoked sort (DF/SORT, SYNCSORT, Other).
