Chaining Document Filters

A previous entry on Text Validation briefly mentions why you should consider using DocumentFilters. A limitation of a DocumentFilter is that you can only add a single filter to the Document. There may be times when you need to filter on multiple conditions. Of course you can always create a new filter and combine the code for multiple filter conditions. However, an easier approach would be to reuse existing filters. That is, it would be nice to be able to chain multiple filters together to act as a single filter.
