You receive XML messages in Microsoft BizTalk Server 2016 by using the XML receive pipeline or a custom receive pipeline with XML Disassembler pipeline component. You may want to configure XML Disassembler pipeline, if DTD processing should be allowed. This improvement adds a new property DtdProcessing to the XML Disassembler pipeline component with the following possible values:
- Parse: DTD processing will be enabled.
- Ignore: DOCTYPE element will be ignored and no DTD processing will occur.
- Prohibit: DTD processing will be disabled, and any incoming XML messages that use DTD will get suspended.
If no value is specified, DTD will get processed by default.
