This is not a bug. You are simply using the wrong tool.
foo {
content: label(xpath, ".");
}
merely specifies how foo is *rendered* on screen in the styled view. You
can still edit it (with the caret hidden inside your custom graphic
representation of foo!) in the styled view. You can also open a tree
view side by side with the styled view (using "View|Add") and edit foo
using the tree view.
Note that the behavior you describe would also happen with the following
CSS rule:
foo {
content: url(image.png);
}
In order to implement ``write-inhibit'', you need to write an
OpenedDocumentHook in Java and declare it in a customize.xxe_gui file.

See
http://www.xmlmind.com/xmleditor/_distrib/doc/gui/openedDocumentHook.html
This OpenedDocumentHook would leverage the readOnly property of XML nodes.
See
http://www.xmlmind.com/xmleditor/_distrib/doc/dev/dom.html#nodeproperties
See
http://www.xmlmind.com/xmleditor/_distrib/doc/api/com/xmlmind/xml/doc/Node.html#putProperty(com.xmlmind.xml.name.Name,%20java.lang.Object)
See
http://www.xmlmind.com/xmleditor/_distrib/doc/api/com/xmlmind/xml/doc/Constants.html#READ_ONLY_PROPERTY
This seems a bit frightening but in fact there is no technical
difficulty implementing such OpenedDocumentHook.
If you want to quickly play with this readOnly property, simply invoke
command setReadonly using "Tools|Execute Command" (keyboard shortcut:
Esc x) or bind this command to a keyboard shortcut.
