The use of the vertical bar seems to break the rendering of the table in the documentation here:
http://rapidjson.org/md_doc_schema.html

Seems like we can fix it by using html encoding for the vertical bars as described in this post:

Change version numbers
Fixed some document linkage
Fix #648

This adds kWriteNanAndInfFlag to Writer to allow writing of nan,
inf and -inf doubles as "NaN", "Infinity" and "-Infinity",
respectively, and kParseNanAndInfFlag to Reader to allow parsing
of "NaN", "Inf", "Infinity", "-Inf" and "-Infinity". This is part
of issue #36, adding optional support for relaxed JSON syntax.

This adds kParseTrailingCommasFlag to allow a trailing comma at the
end of maps and arrays. This is part of issue #36, adding optional
support for relaxed JSON syntax.

Fixed up some wording to the schema documentation
