晋太元中,武陵人捕鱼为业。缘溪行,忘路之远近。忽逢桃花林,夹岸数百步,中无杂树,芳草鲜美,落英缤纷。渔人甚异之,复前行,欲穷其林。 林尽水源,便得一山,山有小口,仿佛若有光。便舍船,从口入。初极狭,才通人。复行数十步,豁然开朗。土地平旷,屋舍俨然,有良田、美池、桑竹之属。阡陌交通,鸡犬相闻。其中往来种作,男女衣着,悉如外人。黄发垂髫,并怡然自乐。 见渔人,乃大惊,问所从来。具答之。便要还家,设酒杀鸡作食。村中闻有此人,咸来问讯。自云先世避秦时乱,率妻子邑人来此绝境,不复出焉,遂与外人间隔。问今是何世,乃不知有汉,无论魏晋。此人一一为具言所闻,皆叹惋。余人各复延至其家,皆出酒食。停数日,辞去。此中人语云:“不足为外人道也。”(间隔 一作:隔绝) 既出,得其船,便扶向路,处处志之。及郡下,诣太守,说如此。太守即遣人随其往,寻向所志,遂迷,不复得路。 南阳刘子骥,高尚士也,闻之,欣然规往。未果,寻病终。后遂无问津者。

ASN.1 Module Definition for the
LDAP and X.500 Component Matching Rules
Status of this Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.

Abstract
This document updates the specification of the component matching
rules for Lightweight Directory Access Protocol (LDAP) and X.500
directories (RFC3687) by collecting the Abstract Syntax Notation One
(ASN.1) definitions of the component matching rules into an
appropriately identified ASN.1 module so that other specifications
may reference the component matching rule definitions from within
their own ASN.1 modules.
1. Introduction
The structure or data type of data held in an attribute of a
Lightweight Directory Access Protocol (LDAP) [LDAP] or X.500 [X500]
directory is described by the attribute's syntax. Attribute syntaxes
range from simple data types, such as text string, integer, or
boolean, to complex data types, for example, the syntaxes of the
directory schema operational attributes. RFC 3687 [CMR] defines a
generic way of matching user selected components in a directory
attribute value of any arbitrarily complex attribute syntax.
This document updates RFC 3687 by collecting the Abstract Syntax
Notation One (ASN.1) [ASN1] definitions of RFC 3687 into an
appropriately identified ASN.1 module so that other specifications
may reference these definitions from within their own ASN.1 modules.

The InformationFramework ASN.1 module from which the MATCHING-RULE
and RelativeDistinguishedName definitions are imported is defined in
X.501 [X501].
The object identifiers used in this document have been assigned for
use in specifying the component matching rules by Adacel
Technologies, under an arc assigned to Adacel by Standards Australia.
3. Security Considerations
This document collects together the ASN.1 definitions of the
component matching rules into an ASN.1 module, but does not modify
those definitions in any way. See RFC 3687 [CMR] for the security
considerations of using the component matching rules.
