daisy3-to-daisy202: generates invalid ncc.html

[ninkisa]

I'm trying to convert Daisy 3 book to Daisy 2, but some of the metadata tags have empty content For example:
In Daisy 3 ncx file the following metadata has content that is not empty

      <meta name="dtb:depth" content="1"/>
      <meta name="dtb:maxPageNormal" content="0"/>

but in the result ncc.html it is :

        <meta content="" name="ncc:depth"/>
        <meta content="" name="ncc:maxPageNormal"/>

Also the generated SMIL file has DOCTYPE = http://www.w3.org/TR/REC-smil/SMIL10.dtd which doesn't exists File not found: http://www.w3.org/TR/REC-smil/SMIL10.dtd

Expected Behavior

ncc:depth and ncc:maxPageNormal to have correct content attribute valid SMIL file
