Hello,
 
I wonder if anyone has experience in constructing a meta-schema or a
meta-model.
 
I wish to build a meta-schema containing various data types and
components which would shape up a form schema. This schema would
obviously differ from one form to another. Lastly, I would have an
instance document which would contain the values for the respective form
fields.
 
To exemplify what I wish to implement - 
 
At the top-most level - i.e. metaschema level, I would have the
following global elements
 
Form, checkboxes, radiobuttons, textfield, combobox and listbox
 
Then, on the schema level, I shape up my form using the above available
components only. Here I should also be able to define the data type of
the field. So I could have -
 
Name - textfield having data type string
Age - textfield having data type integer
Gender - radio button having options Male or Female
Education - listbox containing options School and University
Join Mailing List - a checkbox
 
And finally - I would have an instance document which will only have
values in it as below
 
<form>
<name>John</name>
<age>25</name>
<gender>male</gender>
<education>school</school>
<join_list>yes</join_list>
</form>
 
Any guidance in creating such a three-tier xml package would be much
appreciated...
 
Many thanks,
 
Rahul
