Please note: This site specifically calls out questions about software requirements as being on-topic. Escrow is specifically listed as a non-functional/qualitative requirement on Wikipedia, and I argue that makes it a valid requirements-based question for this site.
Clever. But is it true?
Can the Wikipedia definition of "Non-Functional Requirements" be used as a guiding principle for asking on-topic questions on Programmers?
Note that Licensing, which is on-topic, is also listed in the Wikipedia article as a non-functional requirement. But so is Network Topology, Privacy, Environmental Protection, Pricing, and even "Emotional Factors."
