• The .deb-package lacks the dependency of libxml-xpath-perl (2015-02-23)
• Replace XML::XPath by XML::LibXML2 (2015-02-23)
• The <include/> statement allows only for including stuff from the same <application> namespace. Sometimes access to arbitarary config trees of another application would be nice. Thinking about <import/> or similar. (2015-02-23)
• Some variable replacement mechanism. Like <basedir value=“/var/lib/app”/> and <workdir value=“${basedir}/work”/> . Testcode now runs in mkrepo.
