What is XML Datatype?

Question

eg: if apn is abc.ap1, length of apn IE of create session request should be 7 or 8.?
If it is 8, what will be data type ?
I got little confused after reading specs (3gpp 29.274 clause 8.6 & 23.003 cl. 9.1, RFC 1035 3.3), the APN IE is encoded as one or more labels.

The xml data type lets you store XML documents and fragments in a SQL Server database. An XML fragment is an XML instance that is missing a single top-level element. You can create columns and variables of the xml type and store XML instances in them. The xml data type and associated methods help integrate XML into the relational framework of SQL Server.
