Create a bibliography/glossary-like structures in Latex

Question

I'm making a software requirements document in Latex.

I wanted to make something 'somewhat' easy to use since more people will start to do the same in the company if this gets a good reception.

Using the glossaries package we can create structures like

\newglossaryentry{utc}
{
   name=UTC,
   description=
   {
      Coordinated Universal Time
   }
}

and then, by calling \gls{utc}, it gets compiled and the name field is presented.

(Somewhat like using bibliography)

I was thinking of making structures like this to represent a requirement. That way, we could create a file with the requirements and then call them in the document.

Something like:

Input:

\newrequirement{
   type=Functional
   priority=high
   description={
      app must save the world
   }
   frame={
      detailed description on saving the world
   }
}

Output: by calling \printrequirements

Functional requirements:

        FR1: App must save the world
   Priority: High
      frame: detailed description on saving the world
      ------

        FR2: 
   Priority: 
      frame: 
      ...
        

---

I can't use the glossaries package because it's already in use for the actual glossary.

I've been looking for a way to create such structures with custom fields, so we could decide the print formatting later, but can't say I even know what to look for...

I've created some commands with \newcommand and \newcommandx, is this the way to create something like \newglossaryentry?

I'd appreciate some ideas?

P.S. Now that I wrote the question, I think the best example would be the bibliography package, since it also adds a counter to the entries
