Input -> Parser -> Writer = Input

Test if the above shown chain yield an output document where the content is equal to the original input.

Test that with all combinations of lexer, parser and writer.

xmllint's --format option can be used to standardize the formatting of an XML file so that you can use diff. This may simplify writing the tests.

@Hackerpilot thank you.
This will prove very useful, as it will allow me to test on the entire W3 Test Suite without worrying about formatting issues.

@burner Great news!
I had to change the way <!DOCTYPE nodes are handled, but now the library can input and output them easily. This was the only thing that prevented input -> parser -> writer = input to be tested.
Now make test (test driver at source/test.d) runs the chain on every valid file of the W3C XML Test Suite.
Currently the reported failure rate is ~11%, due to the fact that we don't preserve any whitespace, while xmllint preserves some of them (even if all files are normalized with options --pretty 2 --c14n11).

sweet! Awesome job.

If you have the time, maybe just compare the nodes and there attributes. That might give you a more realistic failure rate, but only if you have time.
