It turns out to be a combination of problems:
1) as Jeff pointed out, it should be xi:include (my error)
2) I needed to remove the --valid option and use --postvalid for xmllint

Also, xmllint puts out the SGML_CATALOG_FILE message (see below) if you
use the default /etc/xml/catalog.  So the non-use of catalogs does not
apply.
