* SA5 load starting
  * SA5 lib load starting
    * Custom lib events 
    * ... 
  * SA5 lib load finished 
  * ... 
* SA5 load finished 

## Identify All SA Classed Elements

Like...

```
<script type="application/sa5+json"> 
{
  "@context": "https://attr.sygnal.com",
  "@type": "ConversionEvent",
  "@version": "0.1",
  "url": "https://sygnal-n8n-u1282.vm.elestio.app/webhook/4eb1125f-ad4f-41d7-8946-a16fe276a8be", 
  "transactionIdType": "auto",
  "type": "contact",
  "item": ""  
}
</script>

## Determine Required Modules

## Load Modules Needed&#x20;

## Execute Modules in Order

* Dynamic Attributes&#x20;
  * First, do config blocks
  * Then attributes&#x20;
