Sorry, I didn't copy my message to the list when I answered Kevin Flynn!
If this can be of any use, hereunder is what I suggested :
Hi, I met the same kind of need, and devised the following work-around.

You are not stuck with a process transformation :
XMLEditors commands can be used recursively to toggle (or create and
set a value to) your "view" attribute.
I use the same (inelegant but effective) way to show/hide features
reflecting, through XPath selectors, the current status of the edited
document.
Here is a snippet of .xxe which might help you :
<binding>
<keyPressed code="F8" />
<command name="toggleAllView" parameter="show"/>
</binding>
<binding>
<keyPressed code="F8" modifiers="shift"/>
<command name="toggleAllView" parameter="hide"/>
</binding>
<!-- selects all elements with attribute "view" -->
<command name="toggleAllView">
<macro trace="false">
<sequence>
<set variable="selectedElement"
expression="//*...@view][1]"/>
<command name="toggleView" parameter="%0"/>
</sequence>
</macro>
</command>
<command name="toggleView">
<macro trace="false">
<sequence>
<choice>
<sequence>
<test
expression="contains('%0','show')"/>
<command name="setViewShow"/>
</sequence>
<sequence>
<test
expression="contains('%0','hide')"/>
<command name="setViewHide"/>
</sequence>
</choice>
<sequence>
<pass>
<test
expression="$implicitElement/following::*...@view]"/>
</pass>
<set variable="selectedElement"
expression="$implicitElement/
following::*...@view][1]"/>
<command name="toggleView" parameter="%0"/>
</sequence>
</sequence>
</macro>
</command>
<!-- Commands to be customized and called for "local toggling" or
creating the attribute when implicit -->
<command name="setViewShow">
<macro trace="false">
<sequence>
<command name="putAttribute" parameter="view
show"/>
</sequence>
</macro>
</command>
<command name="setViewHide">
<macro trace="false">
<sequence>
<command name="putAttribute" parameter="view
hide"/>
</sequence>
</macro>
</command>
