You've got three kinds of elements here:
1) container elements in the eg namespace
2) children of container elements; let's call these border elements
3) descendants of the border elements; let's call these interior elements
If I have understood correctly, you want border elements not to be
unqualified and not to be in the eg namespace. What about interior
elements? I suspect you *do* want to allow those to be unqualified.
Assuming:
- container elements must not have any unqualified attributes
- container elements must not have any attributes in the eg namespace
- border elements must not have attributes in the eg namespace
- border elements must not be in the eg namespace
- border elements must not be unqualified
- interior elements must not have attributes in the eg namespace
- interior elements must not be in the eg namespace
- interior elements may be unqualified
you could write the schema like this:
namespace eg = "http://www.example.com";
namespace noNS = ""
interior =
element * - eg:* {
attribute * - eg:* { text }*,
(interior|text)*
}
border =
element * - (eg:*|noNS:*) {
attribute * - eg:* { text }*,
(interior|text)*
}
container =
element eg:container {
attribute * - (eg:*|noNS:*) { text }*,
(border|text)*
}
