XML for Invoicing - Industry Standards? [closed]

Question

I've come across an application that needs to send invoice information via FTP to various clients. The XML being output by the application is pretty simple however it does not conform to any particular standards (I imagine its home-grown).

Now a colleague has mentioned cXML as a potential standard that we can use for invoice data and its widely available, however its a bit outdated as it uses DTD to validate the invoice data.

So basically I was wondering.: Do you know of any other standards that are currently in use for transmitting this type of information?

Thanks in advance

Try looking into Universal Business Language (UBL).
