validate some "typed" parameters of operations

some parameters of operations, or expressions in the parameter's value are clearly identified :

• xmap attribute is always a "prefix:property" field (one could theoratically put a script there, but it is to be seldom) --> validate that the field exist
• in update properties, we can check that the properties does exist (we cannot control that they are on the type, as we don't know it, but that 's not a problem)
• in "follow lifecycle transition" the transition should exist
• in "Document >Create" the type should exist, the referenced property should exist at least globally
• Document > Get Parent : the type parameter can be checked
• Document["prefix:property"] can be checked when found wherever
• UI > Show Document Create Page
