In the doc project and related project repositories that provide documentation RST source, there will be no Sphinx html builder or  link check builder errors/warnings in the Beijing branch.

Most existing errors / warnings will be eliminated by:

1. Consistent use of a blank line to separate a current block from other markup or directives that imply start of a new block..
2. Using balanced RST inline markup start/stop delimiters
3. Referencing URLs that are valid or use a pattern that link check ignores (see line 380 linkcheck_ignore in sphinx configuration for the current list).
4. Use of the sphinx code-block directives with "source code" that complies with the syntax of the language specified for the code-block.   Source code in an rst file, outside of code-block directive and/or mixed languages within a code-block should be avoided. For example specifying a code-block of type http for a URL that contains some form of macro or variable substitution convention.    If a code-block must contain content that is inconsistent with all code-block supported  language types, specify  "none" as the code-block language.   A before/after example of  code blocks to improve readability and eliminate errors/warnings in html and rst is attached.
