A PHP user is facing a problem using a schema which uses the - (hyphen)
character in element names, as second or subsequent character. We thinks
this is valid XML, according to
http://www.w3.org/TR/REC-xml/#NT-NameChar, where the grammar is:
[4] NameChar ::= Letter | Digit | '.' | '-' | '_' | ':' | CombiningChar
| Extender
[5] Name ::= (Letter | '_' | ':') (NameChar)*
What's actually happening is that he's getting an SDO_PropertyNotFound
exception when he tries to set the property. Within the PHP
implementation, this is resolving to
dop->set<Type>('element-name', value)
which ends up at:
void DataObjectImpl::setSDOValue(const SDOString& path,
const SDOValue& sval,
const SDOString& dataType)
Practically the first thing that method does is to call stripPath(),
which removes the hyphen from the element name - resulting in the
exception later on.
I tried this patch:

which appears to fix the problem. But I expect you'll tell me there is
more to it than that. I know there are existing issues about valid
characters in XPaths. But it seems a shame to prevent this simple
scenario from working because of Xpath.
(NB we're still on the branch. I don't know if this also applies to the
trunk code.)
