Thank you for describing this creative use of "content: attributes();"
--> Another way to suppress generated content is to use content:"";
That is, you could replace:
---
*[condition="unix"]:after,*[condition="win"]:after {display:none;}
---
by:
---
*[condition="unix"]:after,*[condition="win"]:after {content: "";}
---
--> Simpler alternative:
CSS (just this):
---
*[condition="unix"] {
border:0.5px solid #5F9EA0;
background-color:#7FFFD4;
}
*[condition="win"] {
border:0.5px solid #556B2F;
background-color:#FAEBD7;
}
---
Macro (add something like this to your customized docbook.xxe):
---
<binding>
<keyPressed code="F3" />
<command name="setCondition" />
</binding>
<command name="setCondition">
<macro>
<sequence>
<command name="pick"
parameter="'Value of attribute condition:' false 'unix' 'win'"/>
<command name="putAttribute"
parameter="[implicitElement] condition '%_'" />
</sequence>
</macro>
</command>
---
Note that the "pick" command supports autocompletion.
