<p class="MsoNormal">If you actually want to support different types of account numbers and expose that choice to the client (which can supply 1 of N different account ID types), then *maybe* we could add OPTIONAL job-account-type (type3 keyword | name(MAX)),
job-account-type-default (type3 keyword | name(MAX)), and job-account-type-supported (1setOf (type3 keyword | name(MAX))) attributes. But I can't see us including trademarked names as keywords, nor would I like to have a generic "credit-card" keyword since
"job-account-id" by itself is insufficient to authorize credit card transactions.<o:p></o:p></p>

<p class="MsoNormal">Having implemented a couple credit card processing systems over the years for my prior business, I know we would need a lot more attributes and a lot of security language to conform to the current PCI security standards council requirements.

<p class="MsoNormal">Here in Canada, for example, "chip" cards are common and require entry of a PIN or passcode during credit card processing, and there are special rules for ongoing service charges. In the US, few cards use security chips and instead merchants
collect 3 or 4 digit security codes (CVC/CVV) to use in conjunction with the card number, expiration date, and card holder name, and there are specific rules for their use that are slightly different than in Canada.<o:p></o:p></p>

processed (just whether the printer needs transactional information), and since job-account-id will not (or at least SHOULD NOT) be a credit card number or other direct payment identifier, I don't see the point in telling the Client anything other than "I
