Create semi-official XML Schema about geekodoc

[tomschr]

I'm not sure if this is really possible. It can be difficult as RNG allows some content models which are not allowed in XSD.
There is a reason why the DocBook team abandomed the creation of XSDs... 😉

FTR, StackOverflow points at trang -I rnc -O xsd test.rnc test.xsd... (Which toms already tried with not so much success, I think.)

Yes, I've tried to convert it and got the following warning messages:

$ trang -I rnc -O xsd geekodoc5-flat.rnc geekodoc5-flat.xsd

geekodoc5-flat.rnc:333:9: warning: cannot represent required wildcard attribute; approximating
geekodoc5-flat.rnc:338:37: warning: choice between attributes and children cannot be represented; approximating
geekodoc5-flat.rnc:7713:51: warning: choice between attributes and children cannot be represented; approximating
geekodoc5-flat.rnc:7772:51: warning: choice between attributes and children cannot be represented; approximating
/geekodoc5-flat.rnc:10923:5: warning: cannot represent required wildcard attribute; approximating

However, I don't know much about XSD to judge if the schema is really usable. Opening the XSD file in oXygen gives me lots of validation errors (289 items). 😏

I guess, it isn't really of much use. Writing a XSD file is hard and maintaining it even harder. 😉 Well, I can add it to the build chain and integrate it into our geekodoc package, but I guess, nobody would be really happy about that.

Can you try that for Visual Studio Code and see if it works? If you can confirm it works I'm fine and will integrate it. If it doesn't work, I don't see any value of adding that.

Personally, I try to stay away from XSDs as much as I can. 😆

I think, this is not really going to work, so closing for the time being. If you still think, it's a good idea to have a XSD, feel free to reopen the issues.

I agree with prioing this "low" -- but I think it would be good to keep this open, because it would more or less instantly buy us not insignificant editor support.

I've tried it, same error messages with GeekoDoc v2. It takes significant resources and knowledge to create a XSD schema. Not happening now, so closing.
