Consider an XML language WidgetML which uses XHTML as a sublanguage for help messages:
|
<widget type="gadget"> <head size="medium"/> <big><subwidget ref="gizmo"/></big> <info> <head> <title>Description of gadget</title> </head> <body> <h1>Gadget</h1> A gadget contains a big gizmo </body> </info> </widget> |
Meaning of head and big depends on context!
This complicates things for processors and might even cause ambiguities.
The problem is: one common name-space.
