MORE INFORMATION
The BizTalk Server Business Rule Engine improves performance when you handle XML documents by caching the value that is retrieved. Therefore, the value does not have to be extracted from the document every time that it is used. Sometimes, the engine incorrectly uses the value that is cached from a different node.
