392      * I'm not sure for <trace> and <trace_connect>, there may be a bug here
393      * (FIXME: check it out by creating a file beginning with one of these tags)
394      * but cluster and peer create ASes internally, so putting the code in there is ok.
395      *
396      * TODO, There used to be a guard protecting here against
397      * xbt_dynar_length(sg_platf_AS_begin_cb_list) because we don't want to
398      * initialize the models if we are parsing the file to get the deployment.
399      * That could happen if the same file would be used for platf and deploy:
400      * it'd contain AS tags even during the deploy parsing. Removing that guard
401      * would result of the models to get re-inited when parsing for deploy.
402      * Currently using the same file for platform and deployment is broken
403      * however. This guard will have to ba adapted in order to make this feature
404      * work again.
