/*
* xml_behavior_test.c
*
* Tests XML parser behavior for correctness and specification compliance:
*
* 1) A <plist> element must contain exactly one root value node.
* Any additional value nodes after the first root object must
* cause parsing to fail.
*
* 2) Dictionaries of the form:
* <dict>
* <key>CF$UID</key>
* <integer>...</integer>
* </dict>
* must be converted to PLIST_UID nodes during XML parsing,
* including when they appear nested inside other containers.
*
* These tests ensure proper root handling and UID node conversion
* when parsing XML property lists.
