# Re: [xmlblaster-devel] writing a requirement

`Hello,`

It's now the time for me to write requirement about client.flash and client.csharp (demo done, post soon).

I've see some files in xmlBlaster\doc\requirements :
requirement.dtd
requirement.xsd
Perhaps you have a tool which use that files to help for requirement writing ?

`No, we don't have a tool, i use my plain editor.`

The idea is that if we have categorized it with some markup (as in requirement.dtd )
we have more freedom to generate different outputs later.

```Michele has once generated a PDF handbook from all requirements,
but this work wasn't finished.
(The requirements would need to be reworked as quite a few are outdated)```
