Consistent attribute syntax

Would it work to do this? This uses ----- rules that you would see, when writing slides for slideshows

---
class: slideTitle 

# Presentation Title

---
class: slideInspirationalQuote

> Lorem Ipsum - The Quote

---
class: slideList 

# List
1. thing1
2. thing2

This ties into my proposal for metadata attributes

The metadata is placed in attribute of the div tag for that section. As seen in the example Metadata in documents .
