Açıklamalar

Bu sınıf, genel XML nesne modeli olarak değil, güvenlik sistemi içinde kullanılmak üzere basit bir XML nesne modelinin basit bir uygulaması olması amaçlanmıştır. Bu belgede, XML hakkında temel bilgiler olduğu varsayılır.

Bir öğenin basit XML nesne modeli aşağıdaki bölümlerden oluşur:

• etiket, öğe adıdır.

• Öznitelikler, öğesinde sıfır veya daha fazla ad/değer öznitelik çiftidir.

• Alt öğeler ve </tag>içinde <tag> iç içe yerleştirilmiş sıfır veya daha fazla öğedir.

Öznitelik tabanlı XML gösteriminin güvenlik öğelerini ve değerlerini ifade etmek için kullanılması kesinlikle önerilir. Bu, bir öğenin özelliklerinin öznitelik olarak, özellik değerlerinin de öznitelik değerleri olarak ifade edildiği anlamına gelir. Metni etiketler içinde iç içe yerleştirmekten kaçının. Herhangi bir <tag>text</tag> gösterim için türün <tag value="text"/> gösterimi genellikle kullanılabilir. Bu öznitelik tabanlı XML gösteriminin kullanılması okunabilirliği artırır ve sonuçta elde edilen XML serileştirmesinin kolay WMI taşınabilirliğini sağlar.

Öznitelik adı bir karakter veya daha uzun olmalıdır ve olamaz null. Öğe tabanlı değer gösterimi kullanılırsa, formda <tag/> temsil edilen bir metin dizesine null sahip öğeler; aksi takdirde, metin ve </tag> belirteçleriyle sınırlandırılır<tag>. Her iki form da varsa gösterilen özniteliklerle birleştirilebilir.

Etiketler, öznitelikler ve varsa öğelerin metni her zaman büyük/küçük harfe duyarlıdır. XML formu, gerektiğinde tırnak işaretleri ve çıkışlar içerir. XML'de kullanım için geçersiz karakterler içeren dize değerleri bir ArgumentExceptionile sonuçlanır. Bu kurallar tüm özellikler ve yöntemler için geçerlidir.
