+    # <lang [which='language-name'] [other='lang1,lang2...']>  
+    #  Specifies that the block contained within it is a translation 
+    #  for a specific language specified by the 'which' attribute. The
+    #   'other' attribute can be used by itself or in conjunction with
+    #   which to specify this tag _may_ be used as a translation for some

+    # Comment: this seems a bit silly why not just support a list of languages
+    #           e.g. <lang which='l1,l2...'> and ditch the other attribute?
+    #
+    #  Effect:
+    #    The material within the <lang>..</lang> block is stored in the
+    #    specified set of $available_texts hash entries, the appropriate one
+    #    is selected at </translated> time.
+    #
+    #  Pathalogical case handling:
+    #    If a language occurs multiple times within a <translated> block,
+    #    only the last one is rendered e.g.:
+    #
+    #    <translated>
+    #       <lang which='senisoUS', other='senisoCA,senisoAU,seniso'>
