Q&A
| Q1: | Why is it possible to define your own tags in XML but not in HTML? |
| A1: | In HTML, the tags tell the browser what to do to the text between them. When a tag is encountered, the browser interprets it and displays the text in the proper form. If the browser doesn't understand a tag, it ignores it. In XML, the interpretation of the tags isn't the responsibility of the browser. |
| Q2: | How many different data types can be defined in XML? |
| A2: | Since the number of possible tag names is effectively infinite, there's no upper limit. |
