<para>
<see cref="T:System.Xml.XmlDictionary" /> instances are used by WCF when serializing and deserializing SOAP messages. The <see cref="T:System.Xml.XmlDictionary" /> contains string/value pairs which are used to decrease the size of the SOAP message. When serializing a message the value is written in place of the string. When deserializing the message the value is read but the string is written to the message object. <see cref="T:System.Xml.XmlDictionaryReaderQuotas" /> is a class that contains a number of quotas used by the <see cref="T:System.Xml.XmlDictionaryReader" /> class. The most important security feature of the dictionary readers is quotas. A quotas instance must be given to the dictionary reader factory methods. The default constructor creates "secure" defaults (same as encoded defaults), and the class has a static Max property for creating a reader without quotas.</para>

<para>This quota governs the maximum array length that is created and returned by various API calls. It affects special array APIs as well as byte arrays returned from ReadContentAsBase64(). This limit does not affect the ReadContentAsBase64() override that takes an array to be populated with data.</para>
<para>Note that this property value applies to every step of message processing. This includes some steps that can expand the size of a message or message part. In particular, encryption can dramatically increase the size of a message. When setting this value, you must take this into account. </para>

<para>This quota limits the number of bytes that can be consumed by the reader during a single call to Read().</para>
<para>This quota is an approximation, because transformations in the encoding layer happen before this quota is applied. This quota is closely tied to the number of bytes received on the wire at the transport level, but its purpose is to control the quantity of data we receive for each read. In practice, it is used to limit the size of start tags. Because the entire start tag must be buffered to be processed (attributes uniqueness must be verified), the size must be limited to mitigate DOS attacks.</para>

<para>This quota limits the total number of characters in strings that are atomized in the NameTable for the reader. When strings are atomized they are inserted into a NameTable and never removed. This can cause the buildup of large amounts of character data in a NameTable. This quota places a limit on how much data can be buffered in the reader's NameTable.</para>

<para>This quota limits the length of strings that are created and returned by various APIs. When calling Read() and checking the Value property, the reader chunks string values into manageable pieces (when in streaming mode). However, calling ReadContentAsString() concatenates all these pieces and return one large string. In the binary format, if the value of an element node is a sequence of dictionary string IDs then the values of those strings are concatenated. This can be an extremely large expansion and is mitigated by this limit. </para>
