Nesting Rules

1. Proper Hierarchy - Tags must be properly nested
2. Closing Tags - All opening tags must have closing tags
3. Semantic Attributes - Use name, priority, order attributes
4. Consistent Naming - Use lowercase-with-hyphens for tag names

Code Blocks in XML

<template name="Example">
```language
// code here - note: opening ``` directly under tag

Character Escaping

Only in XML attribute values and text nodes (NOT in code blocks):

• < for <
• > for >
• & for &
