  If you need to use the xref:ROOT:properties-component.adoc[Properties] component from a
  script to lookup property placeholders, then its a bit cumbersome to do
  so. 
  For example to set a header name myHeader with a value from a property
  placeholder, which key is provided in a header named "foo".
