The GitHub project dita-community/org.dita-community.common.xslt
(https://github.com/dita-community/org.dita-community.common.xslt)
includes the general-purpose relpath_util.xsl, which provides a pretty
comprehensive set of URL and OS path manipulation functions, including
functions getParent(), getName(), getNamePart(), and getRelativePath().

While this code is packaged as a DITA Open Toolkit plugin, it's just a
normal XSLT2 module. relpath_util.xsl has no dependencies on any other
modules.
