## 含义

factionexprlookup: X4 属性架构类型：基础类型、约束与可选值。

XSD 类型约束 XML，并不声明 Lua 返回值或 event.param 的数据类型。通过架构验证不能证明游戏效果已经发生。

## 架构结构

`libraries/common.xsd`

| 属性 | 值 |
| --- | --- |
| 构造方式 | `union` |
| 联合类型成员 | [`expression`](wiki:schema-expression-b8bc0e4f) |

其他内线工会分支:

| 属性 | 值 |
| --- | --- |
| 构造方式 | `restriction` |
| 基础类型 | [`xs:string`](wiki:schema-xs-string-d5652e9b) |

| 约束 | 值 |
| --- | --- |
| `enumeration` | `faction.alliance` |
| `enumeration` | `faction.antigone` |
| `enumeration` | `faction.argon` |
| `enumeration` | `faction.boron` |
| `enumeration` | `faction.buccaneers` |
| `enumeration` | `faction.court` |
| `enumeration` | `faction.civilian` |
| `enumeration` | `faction.criminal` |
| `enumeration` | `faction.outlaw` |
| `enumeration` | `faction.freesplit` |
| `enumeration` | `faction.hatikvah` |
| `enumeration` | `faction.holyorder` |
| `enumeration` | `faction.holyorderfanatic` |
| `enumeration` | `faction.kaori` |
| `enumeration` | `faction.khaak` |
| `enumeration` | `faction.loanshark` |
| `enumeration` | `faction.ministry` |
| `enumeration` | `faction.ownerless` |
| `enumeration` | `faction.paranid` |
| `enumeration` | `faction.pioneers` |
| `enumeration` | `faction.player` |
| `enumeration` | `faction.scaleplate` |
| `enumeration` | `faction.scavenger` |
| `enumeration` | `faction.smuggler` |
| `enumeration` | `faction.split` |
| `enumeration` | `faction.teladi` |
| `enumeration` | `faction.terran` |
| `enumeration` | `faction.trinity` |
| `enumeration` | `faction.yaki` |
| `enumeration` | `faction.xenon` |

restriction 收紧基础类型的限制；union 接受其中一个类型分支；list 描述由空白分隔的项目。同一个限制中的 enumeration 值互为可选项。pattern 使用 XML Schema 正则表达式，不是 Lua 模式或 JavaScript RegExp。从基础类型继承的约束仍然有效。

## 示例与结果

根据下面的属性页面进行文本示例. 单独从类型名称中推断一个通用可执行的例子.
