ead2002toEADx.xsl: default value 'xxx' is not facet-valid with respect to enumeration

adds parameters to the xslt with default value for  `<control>` sub-elements that are valid with with respect to their enumerations.

currently, the output looks like this

```xml
<control>
...
<eventType>xxx</eventType>
...
<agent>xxx</agent>
...
<publicationStatus>xxx</publicationStatus>
...
</control>
```

`eventType` default is `derived` 
`agentType` default is `machine`
`publicationStatus` default is `inProcess`

But, I missed up and forgot to branch ... so this pull request has the fix for the xmlns issue in it as well...
