make_node <- function(name, children = list(), attr = list()) {
  # Check that children is a list
  # Check that attributes is a named list

    name = name,
    children = children,
    attr = attr,
    class = "r_xml_node"

node <- function(name, ...) {
  parts <- list(...)
  has_names <- names(parts)

    children = parts[!has_names],
    attr = parts[has_names]

This would make it easier to have a symmetric as_list() and as_xml(). However, we need to scope this carefully as we don't want to end up in like XML where you have two alternative representations and each function only works with one.

`as_xml()` generic function to convert R objects to xml
The most important method is for lists and enables full roundtrip
support for going to and back from xmfor lists and enables full
roundtrip support to and from XML.

Closes #137, #143

We can do full round tripping without needing to do this now 1f820d8
