Steps to Reproduce

locals {
  user_attributes = {
    email = {
      name                = "email"
      attribute_data_type = "String"
    }
    "selected_tenant" = {
      name                     = "custom:selected_tenant"
      attribute_data_type      = "String"
      developer_only_attribute = false
      mutable                  = true
      string_attribute_constraints = {
        max_length = 2048
        min_length = 0
      }
    }
  }
}

resource "aws_cognito_user_pool" "name" {
 ...
  dynamic "schema" {
    for_each = { for k, s in local.user_attributes : k => s }
    # no syntax highlighting or intellisense for schema
    #####################################################################
    content {
      attribute_data_type      = schema.value.attribute_data_type
      name                     = replace(schema.value.name, "custom:", "")
      developer_only_attribute = lookup(schema.value, "developer_only_attribute", null)
      mutable                  = lookup(schema.value, "mutable", null)
    }
  }
}

Expected Behavior

Not sure if it's supported, but having syntax highlighting and intellisense would be nice.

Actual Behavior

No syntax hightlighting or intellisense.

Hi @anthonyma94,

Thanks for the report. You're right, we don't currently recognise "local" references within the dynamic block, such as schema.* in your example. This affects completion, hover, go-to-* and semantic token highlighting.

What makes these local references different from other local references we already support (such as count.index, each.*, and self.*) is that apart from the first segment, such as schema above, the rest of the address is entirely dependent on interpolating the supplied expression/variable inside for_each.

I'll rename this as a feature request if you don't mind.
