In my line of work I deal with a lot of the government type contract stuff for defense and military.

If this is in your RFP, it's in in a requirements list that specifies everything that has to be delivered. The military calls the requirements lists CDRL, and one product can have hundreds of CDRLs, each one specifying the requirements of one component. If your design doesn't match the requirements list, it gets rejected and you have to re-do it. And they don't pay you for the re-work.

Before the first production unit was ever built, the contractors who created the designs had to prove they met the requirements list and get government sign off. There are several points along the way where the government sign off has to come, and all of them involve proof that the design, prototype and production units meet every requirement specified in the RFP and requirements lists. So if the RFP says it can store images, it can. End of story.
