When analyzing org.tp23.antinstaller.taskdefs.Installer I found out that setIcons(..) is dependent on antInstallLib and may not be called before setAntInstallLib(..). So there is a logical dependency of these two attributes. The "icons" attribute depends on the "antInstallLib" attribute.
But, as it is said in the XML-Spec (http://www.w3.org/TR/REC-xml/#sec-starttags)::
"... the order of attribute specifications in a start-tag or empty-element tag is not significant."

Due to the fact that an attribute ordering can not be ensured, the dependency of the "icons" attribute on the "antInstallLib" has to be removed.
