Change DD4hep Attribute handling
Using hasAttr(const XmlChar* att)
has proven to be too fragile (as XmlChar is typedefed and can be machine and external dependent).
Change the ActsExtension
to ProtoMaterial
with a different translation schema.
Instead of
<layer_material representing="true" inner="true" outer="false"/>
this will change to
<layer_material surfaces="representing, inner">
etc.
