minor comments

Dear authors.

The primer seems to become a useful document. Thanks!  Here are the minor
problems I have seen while reading it (in reading order):

Köln, Germany: Contains unreadable characters in print out
 (probably the ö).
 And Köln (instead of Cologne) is inconsistent with "Rome"
 (which should be Roma then).

Normalized dates should better be uniform:
2006-12-1 -> 2006-12-01
2006-12-5 -> 2006-12-05
2007-01-6 -> 2007-01-06
2007-01-8 -> 2007-01-08

"Stephen" -> "Stephan"

"collegue" -> "colleague"

"can run queries can be run" -> "can run queries"

"Authors'draft" -> "Authors' draft"
Dates in References: should follow ISO (not: 2006/08/30 and 2006/03/09).
The granularity of seconds might look too technical.

And should not the "References" section be generated (e.g. with W3C
techniques :-) ) that avoid inconsistencies (like the use of "and" in
editor or author lists and initials)?

Greetings
Sven
