    Hi Jamal: You might want to extend the FpML schema by creating your own markup language, e.g. abcML. In other words, abcML would contain the custom elements and attributes and only reference the FpML schema (which stays intact and can be upgraded independently). Here’s what the top of your own schema would look like: That should work for your purpose. Best Regards, Lyteck FpML Technical Analyst ISDA Note: What you describe is a common thing companies want to do. We actually have upcoming FpML training courses in London and New York that teach just that -how to create your own extensions- if you are interested. See http://www.isdadocs.org/conf/conf_indexes/index_12-08-10fpml.html or http://www.fpml.org (training section)

    Thanks Lyteck, Another quick question, what parser normally used to parse FpML with custom tags? Is there any tools available, right now plan to use JAXB tool ( java tools to bind xml to objects ). Implementing Clearing solution for Derivative world using FpML message ( 5.0 ). Each ClearingHouse come up with custom tag inaddition to statndard FpML schema. Please advice me to choose appropriate parser. Thanks, Jamal

    Jamal, The technique described above to create the abcML extension follows W3C schema syntax, hence the same parser that you would use to parse FpML instances would be used to parse your abcML. e.g., Xerces, Saxon just to name a few. Regarding your clearing project, and your particular status example, you might want to look at FpML 5.1 Working Draft 3. There’s a similar status field that was added based on input from major clearing houses. http://www.fpml.org/news/5.1_3rd_announcement.htm (see section 3.3.3.6 of the confirmation view) Best, Lyteck
