Re: [Vala] Fwd: Fwd: XML Serialization

[Daniel Espinosa <esodan gmail com>]

When convert on memory representation of information to XML, may the model
have temporal values not to be serialize; then you need to "mark" what
properties you want to serialize.

For XML you need to establish if your XML serialization includes name spaces
or other information; if the Xml.Node's name is the same of the class' name
or you need a custom one (GtkImage could be <gtkimage> or just <image>); and
the same for Node's attributes.

Childs nodes (other GObjects properties), must include the same information.

Is this class libraries useful for any budy? I haven't time enough to full
time development. I need help to figure out and hack on it as far as my free
time helps.
