Hello Patrick,
First, sorry for the off-topic, but you didn't tell me which mailing list is the right one. I reviewed all of them and from the topic of the list: "This mailing list is for discussing configuration tool development." I thought it was the right one.
Second, I agree that the task of standarizing the way any software get's its configuration can be a huge task. The point I'm trying to make is the lack of guidelines, much less standards of configuring services from their configuration files. Wouldn't it be great if there was a tool developers could use to configure their programs using standard, human readable, easy to understand configuration files? Most services only need a plain, name=value type file so there's no reason why most of them are different.
Doing a quick review of the configuration files for very common services this is what we have:
Service Type
Samba name=value with sections [].
Postfix name=value.
Apache name value with sections <>.
Amd name=value with sections [].
Dovecot name=value with sections {}, and subections.
Grub name=value with sections name value.
Spamassassin name value.
But even for the same service MTA for example, the configuration is completely different from one another: sendmail, postfix, qmail.
You guess is right, I don't have "a whole lot of experience developing configuration systems in software applications", I would say I have some experience. Apart from being a web developer (mainly), I have experience in systems administration, specially *nix. Although I think this is not relevant.
The XML-DTD standard was created to be able to exchange ALL kinds of data, and it does it very well... except for non-structured binary data. I'm sure it can be used to describe most, if not all services' configuration.
The question I'd like to ask you, the experts, is: do you think it is worth? I think it is. At least there should be a guide, or recomendations on this.
Thanks again for your attention. Best regards,
Pedro.

First, this thread is off-topic for this list:
http://fedoraproject.org/wiki/PostIsOffTopic
I'm going to guess you don't have a whole lot of experience developing
configuration systems in software applications. When developing an
application, a lot of consideration must go into the configuration system to
be used. The developer will generally make a selection based upon their
needs, knowledge and available tools. Sometimes, an XML solution might be
the wise choice, but there are also cases where nothing more than a flat-file
with "name=value" pairs is necessary, cases where a more powerful database is
needed, and cases where some other structured format or scripting language
might be needed. The number of factors that must be considered is
astronomical. Making a choice for the wrong reasons can have catastrophic
consequences. There is no one right way, and there won't be in the
foreseeable future.
