Prop can be used to bind to page properties. The binding is two way. Since page properties are also pushed to matching properties in code behind, =this.name and =prop.name are identical when code behind exists. In some cases because of typing, the datatype may change however between =this.name and =prop.name. This is most often in the case of boolean as booleans in page properties are treated as strings but in code behind may be strings or boolean.
