Note that there are a few characters that are not legal in xml.
 Char ::= #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF] /* any Unicode character, excluding the surrogate blocks, FFFE, and FFFF. */
If you run:
declare @v varchar(32)
set @v = '<a>' + cast(0x08 as varchar) + '</a>'
select cast (@v as xml)
You will get this error:
Msg 9420, Level 16, State 1, Line 3
XML parsing: line 1, character 4, illegal xml character
If your csv input list is going to have essentially ascii data this will not be a problem.
[edit - my query was getting mangled, had to replace < with & lt;]
