Next version, to get rid of the split infinitive I added... any more 

XML documents and data often reference other external resources.  Often 
the referencing information is not sufficient to locate the desired 
resource unambiguously, or the resource is not accessible at the given 
location at the time it is required, or it is preferable that an 
alternate resource be used in place of the referenced resource.

For example:

    1. External identifiers may require resources that are not always
available. For example, a system identifier that points to a resource on
another machine may be inaccessible if a network connection is not

    2. External identifiers may require protocols that are not 
accessible to all of the tools on a single computer system. An external 
identifier that is addressed with the ftp: protocol, for example, is not 
accessible to a tool that does not support that protocol.

    3. It is often convenient to access resources using system 
identifiers that point to local resources. Exchanging documents that 
refer to local resources with other systems is problematic at best and 
impossible at worst.

    4. Incoming XML documents may reference customized versions of 
standard XML schemas.  To protect your systems, it is necessary to remap 
  the schema references so that known, trusted copies of the schemas are 

Entity Resolution is the process by which these resource references can 
be mapped to another version of the reference that can be found or that 
is preferred for other reasons.  To address these issues, the OASIS XML 
Catalog specification defines an application-independent entity catalog 
that maps external identifiers and URI references to (other) URI references.

Entity resolution catalogs have already been widely implemented in much 
deployed software.  Promoting the OASIS XML Catalog specification to an
OASIS Standard is crucial for continued interoperability of XML
