Definition of Whitebeam XML Tags
Prevent further MacroTag definitions
The body of this tag is always empty.
This XML tag contains no attributes.
Putting this tag into a Pattern Page will prevent any additional instances
from being processed. Subsequent uses of <rb:macro...
will cause an error in the page generation. This tag would be used in a tag
library (included in the Pattern Page via 'rb:include') that would define a
few macros for use in a template and then disable further macro definitions
for the lifetime of this Pattern Page.
Once macro definitions have been disabled it is NOT possible to re-enable
them for the lifetime of that page generation.
