 * Schema Reader interface is used to read schema from wsdl and derive appropriate package names
 * from targetnamespace. The algorithm for deriving reading packages names from schema is as
 * follows: 1) Read the inline schema defined in the wsdl 2) check if there is any jaxb
 * customization/binding defined namely schemaBinding. if(schemaBinding defined) then read the
 * package name and add that to the package set. else read the targetnamespace convert tns to
 * package and add to pkg set. 3) check if there are any xsd imports or includes then for(each
 * import) read the inline schema or perfor step 1 check if there is any jaxb schemaBinding
 * customization defined if(schemaBinding defined) then read the package name and add that to the
 * package set. else read the targetnamespace convert tns to package and add to pkg set. Do Step 3
 * recursively so we cover Schema imports within import n times.
