11.5.1: Makes it sense to request that something does an xml

As a XML newbie I used 

field Transaction_Date as date xml-node-name "Transaction Date"

and it worked, I got an xml/xsd using TT:write-xml.

But the result isn't valid. May I expect that at least write-xmlschema or write-xml valdates xml rules?

XML Naming Rules

XML elements must follow these naming rules:

• Element names are case-sensitive
• Element names must start with a letter or underscore
• Element names cannot start with the letters xml (or XML, or Xml, etc)
• Element names can contain letters, digits, hyphens, underscores, and periods
• Element names cannot contain spaces
