Updates to support access to multiple blocks, see 7.4.1, 7.38.18 up to 7.38.
16、26; Add VALIDITY attribute to various lexical structures; Support of multi-language images, see 7.18.2.1; In 7.23.1 deleted the restriction of the MENU item list; Syntactical limitation on conditionals in 7.23.2.1 to restrict the MENU layout; Add LIST and delete VARIABLE_LIST of the MENU items in 7.
17、23.2.1; Additional return value data types for METHOD TYPE, see 7.24.2.3; Replace reference by a context specific specification in Table 170; Clarification on KEY_POINTS behaviour, see 7.35.2.4; Add TRANSPARENT to the lexical structure to make the list of attributes consistent, see 7.36.11; Clearifi
18、cation on file behaviour, see 7.36.10; Add in Table A.5 the new key-words; Add the formal EDDL syntax in A.6. Corrections Deleted in A.6 all non-needed constructs using the auxiliary ._listR. These were created by a non-perfect syntax-checking tool. Deleted in A.6 all non-needed “stmt1:“ and “stmt2:
19、“. These were created by a nonperfect syntax-checking tool. Made A.6 consistent about using a colon at the end of a term by amending colons in a consistent way. Deleted not used references.
