Allow writing (and reading) of legacy XML formats in ascii and binary.
This should enable conversion between formats, e.g. legacy to xml and xml to legacy. Internally, we need to fully parse one format and then write out towards the other formats. Additionally, the conversion should allow for (de)compression and conversion: change the compression level of zlib (or remove compression) and change between ascii and binary.
