DateStructLess.xslt

A stylesheet to convert P4 <dateStruct> and <timeStruct> elements into P5 <date> and elements. The version of P5 converted to is the one in the trunk of the Sourceforge subversion repository as of 2006-05-25. It is very likely to change soon.

<!-- Tiny XSLT 1.0 stylesheet that reads in a TEI (P4) file and writes out the same -->
<!-- file with <dateStruct> and <timeStruct> elements converted to P5 <date> and -->
<!-- <time> elements respectively. -->

<!-- We handle the xml:id= and xml:lang= attributes in addition to the expected P4 -->
<!-- attributes in case we are somewhere in a P4->P5 pipeline in which that has -->
<!-- already been done. -->

<!-- The exact= attribute of p4:dateStruct is converted to the precision= attribute -->
<!-- of p5:date. This is likely to produce invalid results, as the values of the -->
<!-- latter must conform to a short enumerated list. -->

<!-- Note that this stylesheet does not (yet) handle the changes in the attributes -->
<!-- of the children of <dateStruct> and <timeStruct>. -->
