The OPAL Discussion Forum

Hi Chris yes this is a nice feature. You can define any number of additional attributes (restricted to real values).

The OPAL element then know this set of attributes and you can write code such as:

if (elem.has("myAttribute"))

process myAttribute ....

fi

In order to turn off the effect, just remove "myAttribute" from the input file.

Hi Andreas,

In the manual, " other: All elements can have arbitrary additional attributes which are not defined below."

This isn't great for error checking - can it be turned off with a switch somewhere?

Thanks,

Chris
