- data is not duplicated so we need to be careful with it. If there
- isn't a name in the XML, then no page is created as
- the function just returns.
-
- From this point on, we're pretty committed as we've allocated an
- object and we're starting to fill it. The name is set first, and
- is created with a strdup to actually allocate memory for it. Then
- there is a case statement (roughly because strcmp requires 'ifs')
- based on what type of parameter this is. Depending which type it
- is, the value is interpreted differently, but they are relatively
- straight forward. In all cases the value is set to the default
- value from the XML and the type is set to the interpreted type.
