XML files with financial statements required by the Mexican government

Hi,

We are generating XML files with financial statements required by the Mexican government.

Once we have the mechanism to generate the XML files we will need to test that the structure and numbers are correct.  I looked into the website of the Mexican government’s IRS-equivalent and did not find any mention of a test website where to submit test files (similar to what the IRS has here in the US).  

Do you have other customers that have made similar inquiries? Do you have any clients that do business in Mexico to whom you can ask about how they are going about testing these files?
