problem with templates

I'm trying to reverse-engineer a schema into a model. As i'm new in XSLT
(especially templates) i have some problem with recursive behaviour of
templates.
the schema (inlining) i'm working on is (in DTD to understand):
----------------------------------------------------------------------
<!ELEMENT BookStore (Book+)>
<!ELEMENT Book (Title, Author, Date, ISBN, Publisher)>
<!ELEMENT publisher(Name,Address)>
<!ELEMENT Title (#PCDATA)>
<!ELEMENT Author (#PCDATA)>
<!ELEMENT Date (#PCDATA)>
<!ELEMENT ISBN (#PCDATA)>
<!ELEMENT Name (#PCDATA)>
<!ELEMENT Address (#PCDATA)>
----------------------------------------------------
My goal is to extract (from the schema corresponding to DTD above)some
information:
1. Any element containing other element is transformed to a class
2. Simple elements within a class are transformed to attributes
which have to give this:
----------------------------------------------------
<model>
     <class name="BookStore" id="1"/>
     <class name="Book" id="2">
             <attribute id="3"name="Title"/>
             <attribute id="4" name="Author"/>
             <attribute id="5"name="Date"/>
             <attribute id="6"name="ISBN"/>
     </class>
     <class name="Publisher">
             <attribute id="7" name="Name"/>
             <attribute id="8" name="Address"/>
     </class>
</model>
----------------------------------------------------
Please tell me what's wrong with my xslt program.
N.B. both my xslt program and the bookstore schema are enclosed with this
message.
Thanks

Here's my schema : bookstore.xsd
