Specify how to hyperlink the depiction of a local element:

"global documentation"

The hyperlink will be generated to the global documentation related to this element component (see "Generate Details | Elements | Local Elements" parameter). If that documentation is not found, the hyperlink goes to the local documentation (of the element's reference definition) in the Content Element Detail section. At last, if that is also not found, the hyperlink will be directed to the definition of this element within the XML schema source. See "Details | Schema Overview | XML Source" parameter.
"local documentation"
In this case, the local documentation (found in Content Element Detail section) will be the first priority; then the element's global documentation; at last, the location within the XML schema source.
