Rationale Documents updated to new format

EUCAST is currently in the process of reviewing and updating the format of all rationale documents. It is a major and very resource consuming task. Three RDs (cefiderocole, ceftriaxone, tigecycline) have now been published in the the new format, one of which did not previously exist. Old versions will be archived and no longer readily available as new RDs are released. The webmaster can on request make an older version available.
