#29152
In the case you hit a limitation of open-source CSS Parser project, which does not forgive such type of syntax errors.
We could produce a special patched version of the CSS parser for you, which ignores the directive, but without an inclusion of the patch to the main development branch of PD4ML. (An inclusion would require a port of the changes to .NET and it is not that trivial for JavaCC auto-generated stuff)
