New Topic: Encoding of value for columns of type BLOB?

A new topic, 'Encoding of value for columns of type BLOB?', has been made on a board you are watching.

You can see it at
http://liquibase.org/forum/index.php?topic=217.new#new

The text of the topic is shown below:

Hi there,

Using the insert tag with a type 'BLOB' I'm able to insert some binary data, e.g.:

<insert tableName="Picture">
  ...
  <column name="data" type="BLOB" value="xyz1234" />
</insert>

But how is the value supposed to be encoded in this case? Does Liquibase (1.9.5 or 2.x) use the encoding of the changelog
or another one, e.g. Base64? (since < is disallowed in attributes, for example)

Because the contents of attributes in XML schema is rather limited, I can't imagine something different than Base64 but
unfortunately the documentation does not touch this point. Can someone shed some light on this topic?

If this is an open issue, I would suggest using an inner element for value instead, because then a different schema type
could be used for the different value types, something like:

<column name="data" type="BLOB">
  <value xsi:type="xs:base64Binary">xyz1234"<value>
</column>

thanks,

Robin.
