Outputting Attributes for Squiz Matrix Assets when they have no Keyword

This is to test if I can output the Description attribute of Squiz Matrix Metadata Field Asset, using the keyword %globals_asset_attribute_description:xxxxxx%. It turns out there is not a Keyword Replacement for this attribute along with many others.

An example of some of the attributes available on a metadata field are as follows:

Available attributes for a Metadata field in Squiz Matrix
This shows the attributes on the description metadata field shown for this site.

Why am I doing this?

So I want to build an interface within Admin Mode and Edit+ that uses a Metadata Field for some setting so I want to use:

Using Keyword Modifiers to target individual attributes

The ^index keyword modifier can be used to output the attribute's of each attribute, such as:

{"attrid":"988","type":"text","value":"Enter a brief description of this page, no more than 155 characters.","is_contextable":true,"use_default":true}

Beautified Output

 {
  "attrid":"988",
  "type":"text",
  "value":"Enter a brief description of this page, no more than 155 characters.",
  "is_contextable":true,
  "use_default":true
}

We can use it multiple times to grab the attribute's attributes

Enter a brief description of this page, no more than 155 characters.

Conclusion

Even though every attribute does not have a keyword replacement, e.g. globals_asset_attribute_description:1234, we can get these values from the globals_asset_data_attributes:1234 and use keyword modifier ^index to target what we do need.
