Xml in packaging system

[Vadim Chekan]

Also it would allow to compete several tools as soon as data format 
(called "schema" in xml language) is stable.
I think this is a good example of a problem not to use xml with.
If this were a talk about sending electronic data and to use something
such as ANSI X.12 v.s. XML, XML would be the best choice. XML
should be best left for electronic data interchange and not application
configurations.
I'm afraid I do not get what you mean. Why do you think that xml has so 
limited applicable area?

You can think about xml as about a tree like data format with custom 
attributes feature. And a bunch of tools provided for format 
verification(schema), query language(xpath), transformation(xsl) etc. It 
does not sound like definition for "electronic data interchange".
Why "interchange" only?
Why not "generic-purposes hierarchical data format"?

Ok. Finaly it can be something else, not xml. Xml is just an example. 
Why I really wrote the mail is to tell which features I'd like to see in 
port system. It is flexible n-level depth tree structure, and some easy 
way to parse port attributes. At the moment I believe xml is good choise 
taking into account features I wish.
