Provide some more information and notes on tags. Not so positive,
though. See *notes* and *tracker/meta-tags.mdwn*.

 This is the difficultmost. Collect YAML meta block *tag* and *tags*
 fields (as scalars or lists) and amend to the mainline tag work.

+## Info
+
+Tags and labels are used to for many things, such as filtering for
+inline. The [tag directive][drtv:tag] is standard usage. Maintenance
+is through [tag plugin][pln:tag].

+
+## Progression notes
+
+Questions, which is execution order? If parsing with *htmlize* happens
+before, that should be a good start.
+
+Possible places for source code: */IkiWiki/Plugin/tag.pm*. After
+copying to local dir, and adding some debug code, this is snippet of
+output:
+
+
+```
+D: tag:import: Run.
+D: pandoc:import: Run.
+D: tag:getopt: Run.
+D: tag:checkconfig: Run.
+D: tag:preprocess_tag: Run for test, test and 0.
+D: tag:preprocess_tag: Run for test, test and 0.
+D: IkiWiki.pm:htmlize: Run for test, HASH(0x563f41723878),
+D: pandoc:htmlize: Run for test
+D: pandoc:htmlize: Pandoc command:  pandoc -f markdown -t json --email-obfuscation=none
+D: pandoc:htmlize: Pandoc command:  pandoc -f json -thtml5 --email-obfuscation=none--filter=pandoc-citeproc
+D: pandoc:htmlize: Return.
+D: pandoc:pageactions: Run for test
+D: tag:pagetemplate: Run for test, test, page.
+D: pandoc:pagetemplate: Run for test and page
+```
+
+Thus it seems tag plugin gets all the execution before Pandoc plugin,
+for pulling all tag related info. This will be a hard one to break.
