fn:best-identifier similar to fn:best-label

[GoogleCodeExporter]

We need a fn:best-identifier which delivers a stable identifier for a given 
topic.

best-identifier should be in following ordering a
1. subject identifier (si)
2. subject locator (sl)
3. item identifier (ii)
if several identifier of the same type are present the shortest should be 
choosen (e.g. there are two si -> choose shortes si regardless of sl or ii).
The returned identifier should be prefixed with its type e.g.
si:http://example.com/something
