This approach is safe but not very satisfactory. Organizations can standardize on a set of tags. This approach cleverly sidesteps the entire problem. This is actually the right solution for many problems. Sales orders, for example, fit a well-defined pattern.
Applications can try to figure out what to do with novel tags.
There are several ways to solve this problem. This solution, however, has its own limitations. You can build a new framework. While each of the solutions above has its place, we'll explore another solution altogether. Our solution calls for enabling the browser or XML tool to look for and download code designed to handle the novel tags and then integrate that code into the application.
