How to compare strings in sightly?

[#1]

Hi Everyone, 

I need help with comparing string data using sightly : data-sly-test Please help me if you know how to do that. This is what I tried but didn't worked.

     <sly  data-sly-test.var1="${abc.xyz.name}"></sly>
     <sly  data-sly-test.var2=" ${'abc.xyz.lmn' @i18n}"></sly>
     <sly  data-sly-test.var3=" ${'abc.xyz.jkl' @i18n}"></sly>

${var1}

${var2}

                            <div data-sly-test="${var1 == var2}">TEST</div>
                            <div data-sly-test="${var1 == var3}">NOT TEST</div>

I got Output as values of var1 & 2 but no output for data-sly-test.
