How do you chain together a series of transformations?
Xalan-Java supports two strategies for chaining together a series of transformations such that the output of each transformation provides input for the next transformation.
* For each transformation in the series, you can set one SAX ContentHandler to process the input, and another ContentHandler to process the output.
* You can also set up a series of parent-child relationships between an XMLReader and one or more XMLFilters.
