Checkpoint 2.3.5.

This exercise has no content in its statement. It should throw a PTX warning during the representations build.

Checkpoint 2.3.6.

This exercise has a single quote in it. A single quote is the first option for a delimiter for perl’s q function which is used by extract-pg.xsl in table cells. So if working, it should move on to the next delimiter option.
