How do I create an XML schema?

I am new to XML and I want to create an XML schema. How would I go about doing this? Is there a tool that generates the schema or do I have to handwrite it? Where can I go to find information about schemas?
Thanks, Donna

Either, depending on your tool.
Some tools aren't quite so good at creating schemas (letting you design them wonderfully, and then proceeding to generate invalid schemas). Fun huh? Borland Together lets you do it. Alot of other tools do too. Schemas are just beginning to really be taken seriously by alot. DTDs are slipping into the background.
I think zvon.org has a good tutorial/reference on schemas, if you're interested. The best way to learn it initially, is to dive in and try and create schemas using your favorite text editor, however.
Have fun.

(Besides a good book) w3schools.com has nice references for all sorts of stuff, including XML Schemas.
By the way, could you replace that underscore in your display name with a space so that it fits our naming policy perfectly, please?
Thanks.

XSDs were a MS invention originally - so MSDN has a lot of useful resources.
