Question about using placeholders in lyx

[Rémi Cohen-Scali]

Hye

I have a question about a feature I need, that I didn't found in LyX, but not sure is it exists or not (my laTeX knowledge is really limited). I'am writing some docs for a products and I 'd like to use kind of placeholder or variable predefined that I could change when the product changes (ex. version, release name or short release name, ... this sort of stuff).
The target format is docbook and I have some entities defined for this purpose (&release;, &release-short;) that I need to use.
Did one of you already use such a feature and could help me ?

Thanks for any help ...
