They define the properties of their parent element - position on the screen, color, texture, etc. In this sense they are similar to traditional xml [[traits]]. | ||
There are two basic data types for properties - numeric and string. A number of Oblivion-specific XML entities are defined for commonly used constants of both types. Particularly useful are the numeric entities "&true;" (numeric value 2) and "&false;" (1), used to with boolean properties like Visible or Targetable. | There are two basic data types for properties - numeric and string.

The Oblivion parser evaluates each property element every frame to obtain the ''value'' of the property (see the operator element page for a description on how they are evaluated). If an object element contains more than one property element of the same type, the last one defined will take precedence. If it contains no property elements for an applicable property, the default value is used (usually zero or the empty string). | ||

*'''ID''' (Numeric) Specifies which part of the internal menu "class" the element corresponds to, for the purposes of updating and accepting player input. For example, the game treats whatever element has an ID of 3 in the Recharge menu as the exit button, regardless of the type, name, or any other property of the element - if it can be clicked on, then doing so will close the menu. Likewise, the element with ID 2 in the Enchantment Settings menu is treated as the effect icon and will have its filename property updated by the game (even if it shouldn't have one). Valid ID values depend on the menu class, but generally range 1-20. Giving an element an ID not recognized for that menu will have no effect, while changing an existing ID will prevent the element from updating or accepting input. | *'''ID''' (Numeric) Specifies which part of the internal menu "class" the element corresponds to, for the purposes of updating and accepting player input.

*'''User#''' (type flexible) Element types beginning in "user" are not in general part of the Oblivion XML schema. They may, however, be recognized by specific menu classes and set to specific values. For example, in most contexts an element of type User4 would be parsed and then ignored. The internal class of the Spellmaking menu, though, will look for a User4 property element that is a child of the root [[ | *'''User#''' (type flexible) Element types beginning in "user" are not in general part of the Oblivion XML schema.

*'''Visible''' (Numeric: Boolean) If true, the element is visible, and if false the element is hidden. Hiding an element will reveal the elements under it (parents or siblings with lower Depth).

*'''Class''' (Numeric) Specifies which internal menu "class" to use for handling input & output to the menu. Values match those returned by [[MenuMode]], but are generally specified using a set of XML entities closely based on the menu name (e.g. "&RechargeMenu;" for the Recharge menu, with numerical value 1049).

*'''Stackingtype''' (Numeric) Specifies whether or not the menu blocks the use of other menus and or the gameplay controls while open.
