"updated=gt=2003-12-13T00:00:00Z"

use underscores instead for ranges, ie

 updated_gt==2003-12-13T00:00:00Z

I didn't understand why '==' is used as a token instead of '='. Perhaps the above suggestion helps with that.


"By default, a selector is treated as an XML QName [W3C.REC-xml-names-19990114] which selects any and all child elements of the entry element which share the same syntax (i.e., the same prefix and localname; the namespace URI is not considered), along with their descendant content if any.
"

I'm no fan of Qnames/XMLNS, but that looks butchered to me. You at least need to figure out what to do with atom in the default ns and atom with atom:.

The spec doesn't say what should happen with acquired information or assumed values (ie, author). I have to assume since you're treating qnames literally, you're not catering for that either.


I'm not sold on the subset XPath arguments elsewhere btw. This language seems designed to match across branches not select subtrees.

A New Internet-Draft is available from the on-line Internet-Drafts
directories.


    Title        : FIQL: The Feed Item Query Language
    Author(s)    : M. Nottingham
    Filename    : draft-nottingham-atompub-fiql-00.txt
    Pages        : 16
    Date        : 2007-12-18
The Feed Item Query Language is a simple but flexible, URI-friendly
  syntax for expressing filters across the entries in a Web feed.  It
  also specifies a mechanism to allow feeds to indicate what types of
  queries are supported.


A URL for this Internet-Draft is:

NOTE: The mail server at ietf.org can return the document in
    MIME-encoded form by using the "mpack" utility.  To use this
    feature, insert the command "ENCODING mime" before the "FILE"
    command.  To decode the response(s), you will need "munpack" or
    a MIME-compliant mail reader.  Different MIME-compliant mail readers
    exhibit different behavior, especially when dealing with
    "multipart" MIME messages (i.e. documents which have been split
    up into multiple messages), so check your local documentation on
    how to manipulate these messages.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
