<!--
/**
 * # Default Attribute
 * We wanted to generalize Tag Arguments ( ), used in some internal Marko tags, 
 * with a syntax any tag can use. So we are introducing the Default Attribute.
 *
 * This assignment happens with no explicit attribute and instead is passed to
 * the child component as "default". It is just a shorthand but it removes a lot
 * of verbosities when the tag conceptually has a main value that is passed to it.
 *
 * All existing tags that accept an argument will use this syntax instead.
