Infinetely stupid question

[GeezerButler]

I am really sorry if this sounds stupid. Namespace is just not my cup
of tea.

Could anybody tell me what is wrong with this xsd file (It has
something wrong with the namespaces)

I am getting the error "The element 'Books' is used but not declared in
the DTD/Schema."

If I remove targetNamespace ="http://calendar/aiman" and
xmlns:myns="htt p://calendar/aiman" and change type="myns:Book Type" to
type="BookType" it works.

-------------------------------------------------

<?xml version="1.0"?>

The schema looks valid. Probably you validate an instance document
against this schema. When you have a target namespace set on a schema
then when you declare a global element like Books in your case then
that is a declaration for an element in the schema target namespace. So
in your instance document you need to place that element in the
appropriate namespace. From your description it seems you are placing
it in no namespace so instead of
<Books>

you should have

<Books xmlns="http://calendar/aiman">
