OPTION_ESCAPE_USING_CDATA [message #676381]

I have an Ecore model with an EAttribute named "rule" that is typed to EString. I am using the default XMI serialization which makes it an XML attribute. I want to use this feature to store XQuery which may contain XML content and special characters.

I added an EAnnotation with source set to ExtendedMetaData and kind => 'element'. Then I set default load/save options to OPTION_USE_EXTENDED_META_DATA to true. Additionally, I set save options for OPTION_ESCAPE_USING_CDATA and OPTION_SKIP_ESCAPING to true. So everything appears to be set up correctly. My expectation is that the XQuery will remain "as-is" containing unescapted '<' and '>' characters, etc. However, I am still seeing these types of special characters getting escaped.

What criteria does the deserializer use to insert <![CDATA[ ]]>?
Is there anything that I can do to ensure that what gets serialized remains "as-is"?

Thanks,

JT

John,

Is it coming out as an element? You can see the option being used in
convertText; it's called by getDatatypeValue for element content...
