In XML it always looks like a string, but interpretation may vary depending on the attribute. Some examples:
offsetX="-5" ... used in <Anchor>, this attribute probably undergoes ivalue = tonumber(value) before being passed to control:SetAnchor(...)
point="LEFT" ... named constant, not sure whether point="2" (since LEFT == 2) would work; but I still think it's converted to integer at some point, ivalue = _G[value]
color="3a6b9c" ... hex color code, may be parsed by a, r, g, b = ConvertHTMLColorToFloatValues(value)
color="INTERFACE_COLOR_TYPE_ALLIANCE:ALLIANCE_DAGGERFALL_COVENANT" ... another way of specifying color; the conversion would look something like:
Lua Code:
local colorType, colorIndex = value:match("(%w+):(%w+)")
local r, g, b, a = GetInterfaceColor(colorType, colorIndex)
I'm not saying these conversions are done in Lua code, I only tried to illustrate how they'd be done in Lua.
