-* sanitize xml, pass through filter to ensure is valid - done but needs testing
-* remote placement of sitemaps --sitemaps -R (probably makes more sense than doing against -Y [filename/wildcard]) - done but needs testing
-* gzip sitemaps - not before testing / after testing
-* issue with master documnts, naming and mapping, check multilingual

-    def sisu_0_57
-      <<WOK
-
-  SiSU 0.57 (a subset of 1.0) is the same as 0.42 with the introduction of some

-
-  :A~ @title by @author
-
-WOK
-    end
-    def sisu_0_42
-      <<WOK
-  SiSU 0.42 (a subset of 1.0) is the same as 0.38 with the introduction of some additional endnote types,
-
-  Introduces some varations on endnotes, in particular the use of the asterisk
-  ~{* for example for describing an author }~ and ~{** for describing a second author }~
-
-  * for example for describing an author
-
-  ** for describing a second author
-
-  and ~[* my note ]~ or ~[+ another note ]~ which numerically increments an
-  asterisk and plus respectively
-
-  *1 my note
-  +1 another note
-
-WOK
-    end
-    def sisu_0_38
-      <<WOK
-
-  SiSU 0.38 (a subset of 1.0) introduced alternative experimental header and heading/structure markers,
-
-  @headername: and headers :A~ :B~ :C~ 1~ 2~ 3~
-
-  as the equivalent of (the superceded)
-
-  0~headername and headers 1~ 2~ 3~ 4~ 5~ 6~
-
-  The internal document markup of SiSU 0.16 remains valid and standard
-  Though note that SiSU 0.37 introduced a new file naming convention
-
-  SiSU has in effect two sets of levels to be considered, using 0.38 notation
-  A-C headings/levels, pre-ordinary paragraphs /pre-substantive text, and
-  1-3 headings/levels, levels which are followed by ordinary text.
-    This may be conceptualised as levels A,B,C, 1,2,3, and using such letter
-    number notation, in effect:
-      A must exist, optional B and C may follow in sequence (not strict)
-      1 must exist, optional 2 and 3 may follow in sequence
-    i.e. there are two independent heading level sequences A,B,C and 1,2,3
-      (using the 0.16 standard notation 1,2,3 and 4,5,6)
-    on the positive side:
-      * the 0.38 A,B,C,1,2,3 alternative makes explicit an aspect of structuring
-        documents in SiSU that is not otherwise obvious to the newcomer (though
-        it appears more complicated, is more in your face and likely to be
-        understood fairly quickly)
-      * the substantive text follows levels 1,2,3 and it is 'nice' to do
-        most work in those levels
-WOK
-    end
-    def sisu_0_37
-      <<WOK
-
-  SiSU 0.37 introduced the file naming convention, that remains in use in SiSU
-  v1 and v2, using the file extensions .sst .ssm and .ssi
-  to replace .s1 .s2 .s3 .r1 .r2 .r3  and .si
-
-  this is captured by the following file 'rename' instruction:
-
-  rename 's/\.s[123]$/\.sst/' *.s{1,2,3}
-  rename 's/\.r[123]$/\.ssm/' *.r{1,2,3}
-  rename 's/\.si$/\.ssi/' *.si
-
-  The internal document markup remains unchanged, from SiSU 0.16
-WOK
-    end
-    def sisu_0_16
-      <<WOK
-
-  SiSU 0.16 (0.15 development branch) introduced the use of
-
-  the header 0~ and headings/structure 1~ 2~ 3~ 4~ 5~ 6~
-
-  in place of the 0.1 header, heading/structure notation
