Run time error XML Parse Error

I get a run time error '-2147217376 (80041020)': XML Parse Error when I run the code the below.  Does anyone know the fix for this?

Sub Create_XSD()
   Dim StrMyXml As String, MyMap As XmlMap
   Dim StrMySchema As String
   StrMyXml = "< BookInfo >"
   StrMyXml = StrMyXml & "<Book>"
   StrMyXml = StrMyXml & "<ISBN>Text</ISBN>"
   StrMyXml = StrMyXml & "<Title>Text</Title>"
   StrMyXml = StrMyXml & "<Author>Text</Author>"
   StrMyXml = StrMyXml & "<Quantity>999</Quantity>"
   StrMyXml = StrMyXml & "</Book>"
   StrMyXml = StrMyXml & "<Book></Book>"
   StrMyXml = StrMyXml & "</ BookInfo >"

   ' Turn off async loading.
   Application.DisplayAlerts = False
   ' Add the string to the XmlMaps collection.
   Set MyMap = ThisWorkbook.XmlMaps.add(StrMyXml)
   Application.DisplayAlerts = True

   ' Create an empty file and output the schema.
   StrMySchema = ThisWorkbook.XmlMaps(1).Schemas(1).XML
   Open "C:\MySchema.xsd" For Output As #1
   Print #1, StrMySchema
   Close #1
