An XML schema defines the structure of a class of XML instance messages. Because this type of schema uses XML Schema definition (XSD) language to define the structure of an XML instance message, and this is the intended purpose of XSD, such schemas use XSD in a straightforward way.roperty schema. A property schema is used with one of the two mechanisms that exist within BizTalk Server for what is known as property promotion. Property promotion is the process of copying specific values from deep within an instance message to the message context.
Types of Acne Scars. As the wound heals, the body sometimes produces too much collagen, which creates a mass of raised tissue on the skin's surface. This type of scarring is called hypertrophic, or keloid, scarring. More commonly, acne causes atrophic, or depressed, scars. Atrophic scars develop when there is a loss of tissue. Ice pick and boxcar scars are two examples of atrophic scars. Inflammation is the single greatest gauge of scar development. The greater the inflammation on the skin, the more likely scarring is to occur.
Scarring is related to age, ethnicity, and the depth and location of the burn. Scars form when the dermal or lower layer of the skin has been damaged. The body forms a protein called collagen to help heal the damaged skin. Normally the collagen fibers are laid down in a very organized manner, but in hypertrophic scars these fibers are created in a very disorganized manner, which gives the new skin/scar a different texture and appearance.
