Chris@55 43 Some notes about the SV XML format. We're very lazy with our XML:
Chris@55 44 there's no schema or DTD, and we depend heavily on elements being
Chris@55 45 in a particular order.

Chris@55 52 visual layers. Layers are considered data in the document;
Chris@55 53 the structure of views that displays the layers is not. -->
Chris@55 54
Chris@55 55 <!-- id numbers are unique within the data type (i.e. no two
Chris@55 56 models can have the same id, but a model can have the same
Chris@55 57 id as a layer, etc). SV generates its id numbers just for
Chris@55 58 the purpose of cross-referencing within the current file;
Chris@55 59 they don't necessarily have any meaning once the file has
Chris@55 60 been loaded. -->
Chris@55 61

Chris@55 66 in a neighbouring dataset element. The dataset must follow
Chris@55 67 the model and precede any derivation or layer elements that
Chris@55 68 refer to the model. -->

Chris@55 77 it has an associated derivation element. This must follow
Chris@55 78 both the source and target model elements. The source and
Chris@55 79 model attributes give the source model id and target model
Chris@55 80 id respectively. A model can have both dataset and
Chris@55 81 derivation elements; if it does, dataset must appear first.
Chris@55 82 If the model's data are not stored, but instead the model
Chris@55 83 is to be regenerated completely from the transform when
Chris@55 84 the session is reloaded, then the model should have _only_
Chris@55 85 a derivation element, and no model element should appear
Chris@55 86 for it at all. -->
