dbhtml_filename — Specifies a filename for a chunk
<?dbhtml filename="filename"?>When chunking output, use the <?dbhtml filename?>
PI as a child of a chunk source to specify a filename for
the output file for that chunk. Include the filename suffix.
You cannot include a directory path in the filename value,
or your links may not work. Add a
<?dbhtml dir?> processing instruction
to specify the output directory. You can also combine the two
specifications in one processing instruction:
<?dbhtml dir="mydir" filename="myfile.html"?>.
