defining dynamic sized tables in XML schema

is it possible? 


more specifically, a simple example: 


i want a 'table' element to have a sequence of 'entry' elements. 
i know you can use minOccur = maxOccur = x, to enforce table to have x 
entry elements in it. 


but this x value needs to be hardcoded in the schema. 


what if i had another attribute in the element 'table' called num_rows. 


is there anyway to reference or link the num_rows attribute to either 
the minOccur or maxOccur properties 
OR 
is there anyway to use restrictions and facets 


in order to define the number of entry elements i want? 


so the schema encompasses all sizes of table in one schema definition, 
based on the value put into the num_rows attribute for an instance of 
the table element, rather then having multiple schema definition for 
different sizes 


hope that made some sense, ive been trying to figure this out for a few 
hrs now, thinking of key contraints, restrictions, minOccur maxOccur 
etc etc... dont know if im missing something or if it simply isnt 
possible in XML schema 


thanks in advance for any help
