Swimlanes in Activity with SALT

Question

I am trying to construct a wireframe / activity diagram to help management understand a flow. I would like to include swimlanes, but salt seems to confuse the compiler(?)

Blow is the script that is generating the error. For bonus points, how do I wrap the Gateway salt in a condition?

@startuml
!unquoted procedure SALT($x)
"{{
salt
%invoke_procedure("_"+$x)
}}" as $x
!endprocedure

!procedure _model()
{+
<b>Product Model
[Buy Product]
}
!endprocedure

!procedure _gate()
{+
<b>Application Gateway
{
Email | "xxx@foo.com   "
. | [Continue]
}
}
!endprocedure

!procedure _ciamLogin()
{+
<b>Corporate Login
{
Email | "xxx@foo.com   "
Password | "***   "
. | [Continue]
. | <i>Signup
}
}
!endprocedure

!procedure _ciamProfile()
{+
<b>Corporate Profile
{
First Name | "......   "
Last Name | "......   "
Country | "......   "
...
. | [Continue]
}
}
!endprocedure

!procedure _appProfile()

First Name | "......   " | [Edit Profile]
Last Name | "......   " | .
Country | "......   " | .

[OK] | [Cancel]
}
}
!endprocedure

!procedure _azureLogin()
{+
<b>Azure Login

}
}
!endprocedure

I used this to resolve my issue

@startuml
!$app="Application"
!$corp="Corporate"
!unquoted procedure SALT($x)
"{{

}
!endprocedure

!procedure _gate()
{+
<b>$app Gateway
{

}
}
!endprocedure

!procedure _ciamLogin()
{+
<b>$corp Login
{
Email | "xxx@foo.com   "
Password | "***   "
. | [Continue]
. | <i>Signup
}
}
!endprocedure

!procedure _ciamProfile()
{+
<b>$corp Profile
{
First Name | "......   "
Last Name | "......   "

...
. | [Continue]
}
}
!endprocedure

if(Is Internal User) then (external)
