Hi all,
For the interest of folks here, just sharing this information.
I've made following configuration settings for the XML schema validation service at
https://www.softwarebytes.org/xmlvalidation/,
1) XML entity expansion limit is set to maximum 1000.
2) While building content model of an XSD complexType, the nodes that are created internally, is set to maximum 2000.
I've thought of doing these configuration settings, since the above cited site is a public facing freely available XML schema validation service.
