I second Paul's idea about looking at the spec for examples. You need more gunk than is in your example - welcome to the wonderful world of XML...
As for auto-determining input data types, there's two reasons we choose to provide a template containing this and other information - if the input file is empty you still need to know the datatype in order to create a layer - the template made it easier to specify exactly which elements contained attribute values. You could certainly write code that "guessed" the information contained in the template. In the end internally you'd end up creating a data structure which contains exactly the information in the template. We just didn't take the coding this one step further, due to lack of time and use cases. I agree that the template is a bit complicated - but at least it lets you parse a GML file. You can probably find other tools which does this for you a bit more automatically (OGR maybe?). At the time we wrote this code none of these were available.
