AW: [docbook-apps] Problem with images given as entity in xhtml output (template process.image)

-- try to eliminate usage of entities in your documents. In XML entities will give you more troubles then advantages

OK, but as far as I understand, the same problem would come up if I would use a @fileref with an absolute filename like " file:/C:/temp/image.png". 

Question is, whether this is a correct URL for an absolute filename. 
If it is not, then there is a problem with the unparsed-entity-uri() function, since it should never return an invalid URL. This would result in a bug report for saxon 6.5 on windows 7.
If it is, then there is a problem with the process.image template, since it should be able to process URLs with absolute filenames.

Thanks,
Frank
