 The {EBNF::Writer} class can be used to write parsed grammars out, either as formatted text, or HTML. Because grammars are written from the Abstract Syntax Tree, represented as [S-Expressions][S-Expression], this provides a means of transforming between grammar formats (e.g., W3C [EBNF][] to [ABNF][]), although with some potential loss in semantic fidelity (case-insensitive string matching vs. case-sensitive matching).
 
-The formatted HTML results are designed to be appropriate for including in specifications.
+The formatted HTML results are designed to be appropriate for including in specifications. If the [Nokogumbo](https://rubygems.org/gems/nokogumbo) gem list available, the resulting HTML encoded grammar will also be validated.
 
 ### Parser Errors
 On a parsing failure, and exception is raised with information that may be useful in determining the source of the error.
