Increase in maximum allowed size in Document Type ID, Element Name

[Theodoros Theodoropoulos]

Hello everyone,

Currently, maximum "Document Type ID" size is 10 chars and maximum 
"Element Name" size is 15 chars. I vaguely remember that these limits 
were even lower in older versions of Invenio (cdsware). Unless there is 
a design reason (ie big and 'ugly' parameters in URLs or unnecessary 
waste in DB tables), I believe that these limits are somewhat 
...limiting and they should probably be increased.
If current Invenio admins/developers think that this could be useful to 
others and easy to implement, I could submit a relevant enhancement 
request ticket.
If, on the other hand, this is not needed to the vast majority and could 
be 'fixed' by simply altering the max allowed size in a DB column, I 
could proceed with the change in my local installation (provided that 
this won't break how things work).

Best regards,
Theodoros
