If Item occurs, then Goal is required, as shown below, where the sentence without a Goal is unacceptable. In this situation, we mark a Requires relation between the two frame elements.\n\n(19) The robbers tied [Paul Item] [to his chair Goal].\n(20) * The robbers tied [Paul Item].\n\nThe Requires relation occurs in almost all frames that have a construal alternation between a symmetric construal, when a single frame element name is used, and an asymmetric construal, when two frame elements with names of the are used. In the former case a simple name of the form [FENAME]s is used and in the latter, two FEs of the form [FENAME]_1 and [FENAME]_2 are used. Some sample frames are Compatibility, Chatting, and Similarity; there are many more."^^xsd:string ;
