Umut,
 
something like this should do it :-
 
 <xs:element name="door">
  <xs:complexType>
   <xs:sequence>
    <xs:element name="start">
     <xs:complexType>
      <xs:attribute name="x" type="xs:integer"/>

      <xs:attribute name="y" type="xs:integer"/>
      <xs:attribute name="z" type="xs:integer"/>
     </xs:complexType>
    </xs:element>
    <xs:element name="end">

     <xs:complexType>
      <xs:attribute name="x" type="xs:integer"/>
      <xs:attribute name="y" type="xs:integer"/>
      <xs:attribute name="z" type="xs:integer"/>

     </xs:complexType>
    </xs:element>
   </xs:sequence>
   <xs:attribute name="width" type="xs:integer"/>
   <xs:attribute name="height" type="xs:integer"/>
  </xs:complexType>
 </xs:element>

Hei *,

I started reading about xml after having found out that it could
work as a db.

Now i am writing a scheme to understand the tree structure. I got stuck

with complexTypes and attributes. My xml file would look like this:

<door width="150" height="300">
<start x="50" y="50" z="0" />
<end x="50" y="-50" z="100" />

</door>

which would be like below as a scheme (except width & height
attributes):

<xs:element name="door">
                   <xs:complexType>
                       <xs:sequence>

                           <xs element name="start">
                           <xs:attribute name="x" type="xs:integer"/>
                           <xs:attribute name="y" type="xs:integer"/>

                           <xs:attribute name="z" type="xs:integer"/>
                       </xs:element>

                           <xs:element name="end">

                           <xs:attribute name="x" type="xs:integer"/>
                           <xs:attribute name="y" type="xs:integer"/>
                           <xs:attribute name="z" type="xs:integer"/>

                       </xs:element>

                       </xs:sequence>
                   </xs:complexType>
</xs:element>

As I have the attributes width and height- in a complexType element

"door", i'd like to  know how i should put them in the element block at
scheme? I couldn't see any examples in web related to this point. Is it
a common design way not to put attributes in the complex elements?
