the claims

The independent claims (the broadest claims) are as follows. In order to invalidate a claim, you need to find prior art that satisfies every stipulation of that claim. (The "publication date" on the patent is listed as 1/2/2004, but I don't know what the priority date is, i.e. the date prior art has to come before...anyone?)

• A computer-readable medium having computer-executable components, comprising:
  • a first component for reading a word-processor document stored as a single XML file;
  • a second component that utilizes an XSD for interpreting the word-processor document, and
  • a third component for performing an action on the word-processor document.
• A method for handling a word-processing document, comprising:
  • parsing the document, wherein the document is contained within a single XML file and includes all of the instructions necessary to display the document according to how a word-processor would display the document;
  • and interpreting the document according to an XSD.
• A system for creating, interpreting, and modifying a word-processor document stored as as single WPML file, comprising:
  • a WPML file;
  • a validation engine configured to validate the WPML file; and
  • a word processor configured to read a WPML file created in accordance with a schema.
• A computer-readable medium having a schema encoded thereon, for a word-processor markup language, the schema comprising:
  • a properties element;
  • a styles element;
  • a body element, wherein the body element comprises:
    • a paragraph element;
    • a text run element including text that is the text content of a word-processor document and is defined by a single tag; and
    • a table element.

What was the first date OpenOffice.org described its XML usage? Does it satisfy the other elements of the claims, e.g. XSD usage?
