Attributes is an array of strings where string is:
AttributeName=Value
and value is single value and attribtues with multiple values are are entered as separate array elements.
The exception to this requirement is if the AttributeName is objectClass in which case the value can be a comma separate list of objectClasses

	Set tRequest=##Class(EnsLib.LDAP.Message.Add).%New()
	Set tRequest.DN = "m-oid=1.2.840.113556.1.8000.2448.2.1,ou=attributetypes, cn=intersystems, ou=schema"
	Set tRequest.objectClass="metaAttributeType,metaTop,top"
	Set tCount = 0
	Set tCount = tCount+1
	Do tRequest.Attributes.SetAt("m-oid=1.2.840.113556.1.8000.2448.2.1",tCount)
	Set tCount = tCount+1
	Do tRequest.Attributes.SetAt("m-name=intersystems-Namespace",tCount)
	Set tCount = tCount+1
	Do tRequest.Attributes.SetAt("m-description=Default namespace a user connects to",tCount)
	Set tCount = tCount+1
	Do tRequest.Attributes.SetAt("m-equality=caseIgnoreMatch",tCount)
	Set tCount = tCount+1

	Set tCount = tCount+1
	Do tRequest.Attributes.SetAt("m-singleValue=TRUE",tCount)
