[Quickfixj-users] Tag order matters?

[Robert N. <rob...@gm...>]

I have a counterparty who’s not using a typical 

Header body trailer structure to their fix messaging 

Ie. In their message tag 17 appears before tag 35

Does quickfixj expect header body trailer order as per the dictionary?

Has anybody ever seen other fix providers who don’t adhere to this standard?
