Open the Eagle Template in older Version creates Errors

[Thore-Krug]

Opening the Eagle Template in a older Version ( 6/7) results in the following non-critical Errors

Warning(s):

Line 7: unknown attribute 'keepoldvectorfont' in tag <setting>
Line 417: Invalid value 'checkStop' for attribute 'name' in tag <param>
Line 418: Invalid value 'checkValues' for attribute 'name' in tag <param>

I am still able to edit and work with these files.
