OASIS catalog support

TopLeaf can use the catalog mechanism as described in OASIS Technical Resolution 9401:1997 (see http://www.oasis-open.org/specs/tr9401.html) to assist in the resolution of entity references.

TopLeaf's support for the OASIS catalog mechanism is subject to the following restrictions:

  • The NOTATION, DELEGATE, BASE and OVERRIDE keywords are ignored.

  • TopLeaf will always use the public identifier to resolve an entity if it can.

  • References to unresolvable secondary catalog files will generate a non-fatal error.

XML catalogs are not supported.
