Inputthinggroups were actually only added around a year ago:
Code:
<inputthinggroup
id="Conflicts">
<inputthing
name="Conflicts"
helptext="Details about conflicts this quality has with other qualities or augmentations">
<it_separator/>
</inputthing>
<inputthing
name="Removed by Cyber/Bio?"
helptext="If this ability will be lost if a specific portion of the character is replaced by augmentations, choose the augmentation types here. For example, many vision-related abilities are lost if the character replaces their eyes.">
<it_taglist group="AugExclude" tag="?"/>
</inputthing>
<inputthing
name="Mutually Exclusive Options"
helptext="If this ability is one of a group (or many groups) of abilities where you may not select more than one of the avaialble options, choose those groups here. For example, there are many skin-based metagenetic qualities that cannot be chosen together. Another example is that you are only allowed to follow a single code of conduct.">
<it_taglist group="MutualExcl" tag="?"/>
</inputthing>
</inputthinggroup>
And to use that:
Code:
<inputthing>
<it_groupref id="Conflicts"/>
</inputthing>
