You're doing some strange things with namespaces here.

The prefix "xsi" is usually bound to the namespace
"";. It's not wrong to bind it to a
different namespace, but it's likely to confuse your readers.

The element "Single" is in namespace "schema1.xsd" (again, not a
particularly good choice for a namespace URI, because relative URIs are
deprecated; but not incorrect). Stylesheet1 selects element Single in
namespace "schema1.xsd" successfully, using the "xsi" prefix to access it.

But stylesheet2 attempts to access an element with local name "Single" in
namespace "schema2.xsd" - and there isn't one. The element is in namespace

Generally, if you want to avoid confusion, it's good practice to use
prefixes consistently - choose a prefix that gives a clue about the
namespace it's bound to, e.g. s1 to refer to schema1 and s2 to refer to
schema2. Otherwise you can spend a long time staring at your code wondering
why it doesn't do what you expect.
