There isn't. That's why it took me quite a while to add a text-only
output mode to the TextExtract recipe.
What I ended up with is a stack of preg_replace rules, each for
stripping a particular markup from the text.
I also used a method I found in MarkupToUnstyled recipe
to convert links into text, by manipulating the $LinkFunctions array.
I did not follow MarkupToUnstyled approach of stripping markup,
which is to first have the text converted to HTML, then to strip the
HTML tags, as I wanted more control to retain some specific markup.
