Invalid ALTO and PAGE export

[stweil]

The exported ALTO and PAGE files are not valid XML. Validators complain, and the PRIMA PageViewer refuses to load such files. Tested example from the GT data set of ÖNB:

$ ocr-validate alto-2-0 ONB_aze_18950706_1.alto 
mXSDFilename: /usr/local/share/ocr-fileformat/xsd/alto-2-0.xsd
mXMLFilename: ONB_aze_18950706_1.alto
ONB_aze_18950706_1.alto fails to validate because: 

cvc-id.1: There is no ID/IDREF binding for IDREF 'Times_New_Roman_4.5_______'.
At: 1:103402

$ ocr-validate page-2013-07-15 ONB_aze_18950706_1.xml 
mXSDFilename: /usr/local/share/ocr-fileformat/xsd/page-2013-07-15.xsd
mXMLFilename: /tmp/ONB_aze_18950706_1.xml
ONB_aze_18950706_1.xml fails to validate because: 

cvc-complex-type.2.4.d: Invalid content was found starting with element 'TranskribusMetadata'. No child element is expected at this point.

One of the two formats is fixed now.

• [x] ALTO XML
• [ ] PAGE XML

For PAGE XML we need to publish a new XSD. But this does not mean that it can be loaded by the PRIMA PageViewer.
