{{pnw-start}} contains <poem><nowiki> {{pnw-end}} contains </nowiki></poem> {{pnw-start}} some wikitext here {{pnw-end}} some wikitext is rendered as there was no <nowiki> block. Test case: http://test.wikipedia.org/wiki/User:Danny_B./Bugs/Nowiki
This is expected behavior due to the way the parser works internally; tags like <poem> and <nowiki> are all expanded before templates and parser functions. Thus, your {{pnw-start}} is creating new <poem> and <nowiki> blocks with no content that are immediately closed by the parser at the end of that template.
