| XML/SGML error rules: predefined pattern variables | |||||
| Prerequisite Concepts | Related Syntax | ||||
Many of the built-in local variables in markup-error rules are also provided as pattern variables, for compatibility with past releases. Use of these pattern variables is deprecated.
Unlike programmer-defined pattern variables, these pattern variables must always be heralded with the pattern keyword in contexts where heralding would usually be optional.
The pattern variables are #class, #message, #additional-info, #recovery-info, #file-name, and #line-number.
The is specified test will always be true for these built-in pattern variables except for #additional-info and #recovery-info, which are not present in all messages.
