Thanks for your reply.
I'll have to admit that I overlooked the hint for "the asciidoc/xmlto toolchain" because it was in a separate paragraph instead of another item in the system requirements enumeration. (The tool's version number does not look promising so far.) I rebuilt Git on my system because I was notified that a newer release became available.
