Subject: [PATCH] Widen simpleValue to accept native numeric and boolean
 literals

xs:string as the sole encode target rejects a Python float/int/bool
passed straight through xmlschema, forcing every caller to pre-cast
to str even though any text is already valid content here. Union
member order keeps xs:string first, so decode() still always
returns str and no downstream consumer needs to change. Verified
zero validity change across all 330 existing .ids files and all 37
IfcTester schema tests still pass with the patched schema swapped
in. Fixes buildingSMART/IDS#342.
