title: SOLUTIONTYPE option for Paypal Express Checkout in mobile web
body: <p>What we expect are buyers can pay with credit card without having PayPal account.</p>
  
  <p>But there is a conflict in Paypal documentation system we not really understand:</p>
  
  <p>1, As the document "SetExpressCheckout API Operation (NVP)", we must set SOLUTIONTYPE option to "sole".</p>

  <p>2, In the document "Express Checkout on Mobile Devices", they said that "SOLUTIONTYPE" must be set to "mark".</p>

  <p>Does that means, in mobile web, Paypal does not allow to make payment without Paypal account? I think no, because with "SOLUTIONTYPE" set to "sole", we can pay with Credit card in almost cases.</p>
  
  <p>What is the right way to do here?</p>
  
  <p>Thanks for your advice.</p>
