It's not as clear as it could (should) be, but apply's doc says this:
The timestamp of each source file is compared to the timestamp of a target
file which is defined by a nested mapper element. At least one fileset and
exactly one mapper element are required.
While ExecOn says:
The files and/or directories of a number of FileSets are passed as arguments
to the system command. At least one nested <fileset> is required.
Subtle, but there if you read between the lines...
