For <import>s and xsi driven document loading, _xmlCtxtReadFile_ is used
 - in xmlSchemaAcquireSchemaDoc. So there might be a difference in
loading the main schema and <include>s, compared to loading an <import>.
Anyway, I think using xmlCtxtReadFile could be avoided, if this is the
one which makes trouble.
