I've noticed that the display
method will still show DTDs and PIs and SSIs and comments. I'd appreciate any feedback as to whether these should be discarded.
The display method takes a number which represents the depth of tags to show. If you give it 0, no tags are shown. If you give it 1, the top-most layer of tags is shown. (-1, or no value, expands all tags.) Should all non-text items be included in this filtering? Or just tags?
