Default option values

The default value of an option, and the value of a combining numeric option, gets inserted directly into the generated code without any further interpolation, as is. It can be a constant, a preprocessor symbol, or an expression:


 <!-- ... -->


String values must use quotes.

	  <descr>Report's name</descr>
	  <hasvalue />

Default class values typically require the use of a constructor call.

          <descr>Key's expiration</descr>
          <hasvalue />
          <default>x::ymd::interval("1 year")</default>
