You need tools to get the job done. We have them.
You only get so far without the right software tools. While you can look at ReqIF with an Text- or XML-Editor, it won't get you far.
We developed ReqIF Studio, and related plugins. Studio is based on the Open Source Eclipse Requirements Modeling Framework (RMF). So you know that you can tinker with the software if the need arises.
