| support. Many do not provide support for debugging of stylesheets, | |
| and thus can't be used for debugging. XSL Tools provides basic | |
| support for Xalan, and can be used as a guide for adopters on how to | |
| implement their own specific debugging support for other processors. | |

| functionality. However there are a few things that Xalan does not | |
| suppor that other processors do.</p><div class="orderedlist"><p class="title"><b>Xalan Debugging Issues</b></p><ol type="1"><li><p> | |
| <span class="emphasis"><em>Breakpoints</em></span> | |
| - Xalan does not support stopping at Global Variables or | |
| Parameters when a debugging session is started. It will | |
| automatically start at the first template. Break points must be | |
| placed in templates to be honored. The reason for this is that | |
| Xalan lazily initializes the variables only when they are first | |
| used. | |
| </p></li><li><p> | |
| <span class="emphasis"><em>XSLT Text elements</em></span> | |
| - Xalan does not send notifications of xsl:text elements. These | |
| are skipped over when debugging. | |
| </p></li><li><p> | |
| <span class="emphasis"><em>Built In Templates</em></span> | |
| - Xalan does provide notification when the built in templates are | |
| called, but currently the debugger does not support or display | |
| stepping into these templates. | |
