Simple stylesheet adjusts the attributes of <date> and elements.

<!-- Tiny XSLT 1.0 stylesheet that reads in a TEI (P4) file and writes out the -->
<!-- same file with the attributes of <date> and <time> adjusted to P5 flavor: -->
<!-- value= -> when=     -->
<!-- certainty= -> cert= -->
<!-- zone= is dropped    -->
<!-- The output of this stylesheet is not P5-conformant XML; in fact, even the -->
<!-- elements we are changing may not be valid P5. This is because although we -->
<!-- move all the bits of information to the right place, it may still be in   -->
<!-- the wrong format. E.g., a <date value="ca.1948" certainty="moderate"> will-->
<!-- become <date when="ca.1948" cert="moderate">, which has 2 invalid at-     -->
<!-- tributes. -->
