The condition element can be used to create dependency rules using several attributes defined in the standard for other elements.
E.g.:
Dvendor, Dname, … attributes can be used for creating a dependency rule on a <device> elementCvendor, Cbundle, .. attributes can be used for creating a dependency rule on a <component> elementBvendor, Bname, .. attributes can be used for creating a dependency rule on a <board> elementHvendor, Hname attributes can be used for creating a dependency rule on a <part> element
At present, in the standard, among the <device>, the <component>, the <board> and the <part> elements, only the <component> has the attribute condition.
Hence, a condition can be used only to create a dependency rule between a <component> element and the other elements (another <component>, a <device>, a <board> and a <part>).
No other kind of dependencies can be created.
E.g.: there is no way to describe in the PDSC file the dependency between boards (e.g. a daughter board working only when mounted on a specific mother board) or between a board and a part or a device (and vice-versa).
Adding the condition attribute also to board, device and part elements, could allow a pack developer to have all the tools in the standard for describing all the possible dependencies among the defined elements.
