I suspect it's just hard to code, special properties are implemented 
completely differently.  It would be easier to write a separate 
Special:Special_properties that walks the hardcoded list of special 
properties, but some users have complained about an excess of SMW 
special pages.

In SMW 1.0, the property page for a special property displays "This is a 
special property with a reserved meaning in the wiki."  But it doesn't 
list pages using the special property as a regular property page does (I 
filed enhancement request 9748).  Nor can you query special properties 
in a semantic search.

It's a great question.

The list is towards the bottom of SMW_LanguageEn.php , see the latest at
<http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/SemanticMediaWiki/languages/SMW_LanguageEn.php?view=markup>
$m_SpecialProperties:
   Has type
   Equivalent URI
   Subproperty of
   Display units
   Imported from
   Corresponds to
   Provides service
   Allows value

$m_SpecialPropertyAliases:
   Display unit

I added a section to the help, 
http://ontoworld.org/wiki/Help:Annotation#Special_Properties ,
there's a Category:Special_properties for them, and most are documented 
on ontoworld.org.
