- Is there any support for floating point numbers (e.g. Double)?

XML does not (as far as I know) have any built-in concept of floating point numbers, so neither does HaXml. However, within HaXml you have the full power of Haskell available to you, so if you wish to read, write, or process Doubles from/to some string content (or element attributes), you can probably code it yourself quite easily.

In case of Haskell2Xml, what about a conversion like this: <double value="123.45"/> Is this easy to implement? Regards, Christian
