= Simple Advanced Rendering Test

This is a simple test document to verify that Alexandria's advanced rendering features are working correctly.

== Math Test

Here's a simple math expression:

[stem]
++++
E = mc^2
++++

And a more complex one:

[stem]
++++
\int_{-\infty}^{\infty} e^{-x^2} dx = \sqrt{\pi}
++++

== PlantUML Test

A simple sequence diagram:

[source,plantuml]
----
@startuml
participant User
participant System
User -> System: Hello
System --> User: Hi there!
@enduml
----

== BPMN Test

A simple BPMN process:

[source,bpmn]
----
<?xml version="1.0" encoding="UTF-8"?>
<bpmn:definitions xmlns:bpmn="http://www.omg.org/spec/BPMN/20100524/MODEL">
  <bpmn:process id="Process_1">
    <bpmn:startEvent id="StartEvent_1" name="Start"/>
    <bpmn:task id="Task_1" name="Test Task"/>
    <bpmn:endEvent id="EndEvent_1" name="End"/>
    <bpmn:sequenceFlow id="Flow_1" sourceRef="StartEvent_1" targetRef="Task_1"/>
    <bpmn:sequenceFlow id="Flow_2" sourceRef="Task_1" targetRef="EndEvent_1"/>
  </bpmn:process>
</bpmn:definitions>
----

== TikZ Test

A simple TikZ diagram:

[source,tikz]
----
\begin{tikzpicture}
  \draw[thick,red] (0,0) circle (1cm);
  \draw[thick,blue] (2,0) rectangle (3,1);
\end{tikzpicture}
----

== Conclusion

If you can see:
1. Rendered math expressions
2. A PlantUML diagram
3. A BPMN diagram placeholder with source
4. A TikZ diagram placeholder with source

Then the advanced rendering is working correctly!
