%*.inclusion; Parameter Entities — Control SGML inclusions
Used to control the inclusion declarations on elements with inclusions.
The %*.inclusion; parameter entities parameterize element inclusions. You can selectively include or remove elements from the inclusion by changing the appropriate parameter entity. For example, if you remove BeginPage from the %ubiq.inclusion; parameter entity, it is no longer included everywhere in DocBook.
In the XML version of DocBook V4, there are no inclusion entities because inclusions are not part of XML.
