When the hyperlink appears on a WSDL/XSD definition/component name, it would be helpful to use the link tooltip to quickly see what a namespace this component belongs to.

This might be particularly useful when the WSDL/XSD files you document define many components with equal local names, however, in different namespaces and no prefixes are defined for those namespaces at that.

This parameter allows you to generate such tooltips. When it is selected (true), the titles of hyperlinks on component names will include the namespace URI of those components, as shown on the following screenshot:

But note that since the namespace URIs are typically rather long strings, when added to each hyperlink, they may considerably increase the size of the generated HTML files. That's why this parameter was introduced: to be able to switch them off.
