Reverse Auction Defined. You probably think you have a good understanding of how most auctions are done. For example, you may have bid on a product you found on eBay. If another person wants the same item you want, she may bid higher than you to get it. Of course, if you still want the item bad enough, you may bid higher yet.
Custom Data Types: Ability to Create them in Setup. I would like to create my own data type in SalesForce. When we create a New Field, we have to choose from the built in options for example, Date, AutoNum, Checkbox, Picklists, text, lookup, etc.
Using non-standard parameter data types in Powershell advanced functions. It is OK to use custom .NET types as long as you use something like the cmdlet Add-Type to load the assembly that defines the custom type. However in this case, the assembly, System.Xml, is already loaded. Your problem arises because the type you specified is a private type i.e. only visible within the System.Xml assembly.
