* things i want
- vim style folds (setup like my .org mode like folds) working in both
  - vim
  - emacs
- elastic search
- outputs
  - docbook
  - asciidoc
- odt to sisu form?
- description of the focus of sisu as a smarttext, compared to
  - asciidoc --> docbook;
  - markdown --> natural writing, visually meaningful
  - sisu --> identify document structure & objects
* proposals/additions

** TODO [#B] markup indicate objects language where other than document default
at end of text object mark language from language code list (SiSU_is[:language_list_regex]) ~:ja

to mark subsequent objects as being of a particular language ^:~(SiSU_is[:language_list_regex])$
:~ja
to return to language default ^:~-$
:~-
** TODO [#B] markup syntax code block, indicate syntax of code block :feature:
``` code:ruby

** TODO [#C] colored boxes round text :feature:ponder:
    ``` box:red              (select color of box)
    ``` box:warn ``` box:tip (some default boxes? decide)
    ``` box:red:"Warn"       (select color and lead text of box, else instead
          select color box & use regular single line bold markup ^!_ Warn$)

** TODO [#D] blockquotes implement? :feature:ponder:
    ``` quote
    not sure how best to represent

** TODO [#D] bibliography            :feature:ponder:

** TODO speaker, as e.g. play (irc?) :feature:ponder:
    ``` Ophelia:
    ::Ophelia

** TODO [#F] time stamp (e.g. for irc, video text?):feature:ponder:
    ``` 04:03
    ``` 04:03 ... 07:12
    ``` 04:03 + 03:09
    ``` 12:04:03
    ``` 12:04:03 ... 12:07:12
    ``` 12:04:03 + 03:09
    probably not worth the effort, as time stamp is an alternative
    identifying number (to ocn, and ∴ sisu objects not ideal)

** TODO book index, alternative based on search within text


* Document Abstraction :sisu:doc_abstr:

** TODO [#D] XML middle layer?

*** XMLda sisu
  consder alternative sisu layer in XML

*** TODO [#D] RelaxNG sisu

* Output :sisu:output:

** New outputs to consider
*** elasticsearch
*** JSON for elasticsearch

To validate a book.xml file using xmllint, run the following command:
$ xmllint --postvalid --xinclude --noout book.xml

The default location where xmllint will look for the catalog file is
/etc/xml/catalog. Alternatively, you can set the environment variable
XML_CATALOG_FILES to define another default location for catalog
files. Once you’ve got the DTD and catalog set up locally, you can
validate as before:
$ xmllint --postvalid --xinclude --noout book.xml
