Do a schemas validation of the given resource, it will use the SAX streamable validation internally.

Validate a branch of a tree, starting with the given @elem.

void * user_data)
Validate an input based on a flow of SAX event from the parser and forward the events to the @sax handler with the provided @user_data the user provided @sax handler must be a SAX2 one.
| ctxt: | a schema validation context | | input: | the input to use for reading the data | | enc: | an optional encoding information | | sax: | a SAX handler for the resulting events | | user_data: | the context to provide to the SAX handler. | | Returns: | 0 if the document is schemas valid, a positive error code number otherwise and -1 in case of internal or API error. |
