Hi hbradshaw,

as I pointed out in my earlier post, you should choose either

Tr(
    -attr => "value",
    "-foo-bar" => "baz"
)
[download]

ie, attributes have leading hyphens, are quoted if contain inline hyphens, and are not surrounded by {} brackets,
or

Tr({
   attr => "value",
   "foo-bar" => "baz"
})
[download]

ie, attributes have no leading hyphen, but are contained within {} brackets, making it an anonymous hash. Strings with inline hyphens should still be quoted

The easiest way to fix your code above is to remove the {} brackets from within your Tr().

hope this helps
