397      * That is, after the last <config> tag, if any, and before the first of cluster|peer|AS|trace|trace_connect
398      *
399      * I'm not sure for <trace> and <trace_connect>, there may be a bug here
400      * (FIXME: check it out by creating a file beginning with one of these tags)
401      * but cluster and peer create ASes internally, so putting the code in there is ok.
402      *
403      * TODO, There used to be a guard protecting here against
404      * xbt_dynar_length(sg_platf_AS_begin_cb_list) because we don't want to
405      * initialize the models if we are parsing the file to get the deployment.
406      * That could happen if the same file would be used for platf and deploy:
407      * it'd contain AS tags even during the deploy parsing. Removing that guard
408      * would result of the models to get re-inited when parsing for deploy.
409      * Currently using the same file for platform and deployment is broken
410      * however. This guard will have to ba adapted in order to make this feature
411      * work again.
