title: Validate IBAN using XSLT 2.0?
body: <p>is it possible to write an XSLT function which can do the basic IBAN Mod-97 check?</p>
  
  <p>From Wikipedia:<br>
  1. Move the four initial characters to the end of the string.<br>
  2. Replace each letter in the string with two digits, thereby expanding the string, where A=10, B=11, ..., Z=35.<br>
  3. Interpret the string as a decimal integer and compute the remainder of that number on division by 97.  </p>
  
  <p>If the remainder is 1, the checks digits test is passed and the IBAN may be valid.</p>
  
  <p>Thanks.</p>
