The following pattern limits the number of leading zeros to up to 2:

<?xml version="1.0"?>  
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> 
    <xs:simpleType name="myByte"> 
      <xs:restriction base="xs:byte"> 
        <xs:pattern value="0{0,2}1?5?"/> 
      </xs:restriction> 
    </xs:simpleType> 
</xs:schema>
