+# EXPERIMENTAL DRAFT
+
+This is the STIX specification in asciidoc format. This is an experiment and *IS NOT* an official version of the STIX specification.
+
+Specification development in asciidoc has multiple advantages over editing the document in an online graphical editor.
+* transparency - every document change is publicly visible as a git commit.
+* ease of maintenance - style changes and changes to common text can be quickly and automatically made rather than editing each instance individually by hand.
+* ease of validation - link checkers and other tools can be automated to ensure document currrency. Code examples can be held externally to document so that they can be validated by the stix-validator automatically, so that errors don't creep into the documented examples.
+* ease of use - commonly consumed values, such as vocabulary overviews can be held in included documents and consumed directly rather than extracted from the document.

+Generate HTML
+```bash
+asciidoctor  -v --failure-level INFO -a stylesheet=stix.css stix-v2.1.1.adoc
+```
+
+Generate DocBook
+```bash
+asciidoctor  -b docbook -v --failure-level INFO -a stylesheet=stix.css stix-v2.1.1.adoc
+```
+
+Generate docx
+```bash
+pandoc -r docbook -t docx -o temp-v2.1.1.docx stix-v2.1.1.xml
+```
+Open the coversheet and import the temp-v2.1.1.docx file.
