 How to use the BDML source pack:
+* download a copy of the source pack;
+* copy the 'bdml' folder to your source repository inside the documentation folder;
+* create a hierarchy of BDML documentation files that reference BdmlHtml.xsl;
+* reference the bdml-html.css CSS file / syntax highlighting files and/or your
+  own CSS / Javascript in your BDML documentation files;
+* view the BDML pages by:
+    - directly loading the BDML files in your browser; or
+    - creating a build step that transforms the BDML hierarchy into an HTML
+      hierarchy via an XSLT 1.0 processor.

+If directly loading local BDML files, browser local XSLT file loading will be
+need to be enabled. Direct loading is not supported in IE/Edge browsers.
