xml tags with *

Hello,

It seems that one cannot have tags with "*" embedded in them. I have an
xml tag like so:-

<Attachment::*::sisp_db_valnvarchar>
test.txt
</Attachment::*::sisp_db_valnvarchar>

However the MS-XMLDom object is failing to load this. It works when i
replace the '*' with a '~'. Is this behavior valid ?

Thanks in advance for your help.
