Hi,
I apologise for posting this thread twice but I am really having difficulties in adding custom fields. Can this be done in the .impl files? How?
Thank you
Ben

I am still unable to find a solution to this without altering the >FIXML base schemas. Can anyone help? Many thanks- Ben

Hi, I read the post regarding this from Mark Sipos but I am still
unclear of this process. I am still a newbie to FIXML so any help would
be apprediated! I have managed to extend and restrict enumerations using
the -impl files with many thanks to Mr. Stowski and his examples.
Although I am still having difficulties when it comes to adding a new
custom field. In our allocation instruction message we have an added
field called ‘CustomTag’ which is an empty complex type with attributes
of ‘CustomAuthDt’ and ‘CustomStrategy’. I have no problem defining the
attributes in the fields-impl file, but when it comes to extending the
message I can only do so in the components base file. How can I use the
impl-files to add this extra element? Would anything else in the message
have to change as a result of this new field?

Hi,

The are quite extensive examples of extending the FIXML Schema on http://www.fixprotocol.org/documents/741/FIA_Extensions-4-4-FIA-1.zip

The extension here are those generated by the futures industry to extend FIXML.

I think there will be samples of most types of extension within these files.

Hope this helps
